Re: [M100] File transfers (was Update on my M100 and REX)

[Mike Stein]

Well, if Mark reads this maybe you can solve his minicom problem together.

Sounds like you've got an XP configuration issue with that com port, not 
specifically a problem with Hyperterminal; if you feel like spending some time 
on it there's lots of information out there (some of it even useful ;-)

As John mentioned,Teeny uses very little RAM (that's why it's called TEENY ;-) 
but TS-DOS in ROM uses none at all; try TEENY or TS-DOS in RAM to get the hang 
of it and even if by chance you can't get REX working TS-DOS in ROM will let 
you transfer all file types with no RAM overhead (and instant access that 
survives any Reset).

And yes, Mcomm is also an option; note that it requires a 'full' null-modem 
whereas TEENY etc only need a 3-wire cable.

  I'll try to answer these questions best I can.


  Can I managed 19,200bd? Yes I can, this is using a REAL rs-232 port. I built 
a home computer specifically for backward compatibility with old software. It 
runs windows xp and Ubuntu. I also have a USB - serial adaptor for 
transferring images files over to my bbc micro. I've found this adaptor works 
really well with the M100. In fact it is the only way I have found I can use 
Windows and my m100 side by sides. For some reason windows will not use the 
onboard serial port, it just locks the system up. I've tried all sorts and 
short of formatting the system and reinstalling windows, I can't think of a 
solution.


  I am solely using TELECOM to transfer files, I would like to use other 
software, but because of the computers limited memory. I don't want to go 
filling it up with apps and be unable to use the M100 for writing. This why I 
bought a REX, so I have more space then I could shake a stick at and be able to 
open to potential of the computer.


  I hope that answers your questions, if I've missed anything just let me know!

Hi James,

 At present I'm using a null modem cable, linked to a Linux box running 
minicom.

- Can you run at the maximum 19,200bd? 
- If not, what is the fastest that works for you?
- Is your Linux box using a 'real' RS232 com port or a USBRS232 adapter?

If yours is working properly maybe you can help Mark Wickens; he's also 
using minicom but is only getting reliable transfers at 1200bd or below (he's 
also on your side of the pond).

 Hyper terminal was a nightmare!

Any idea what made it a nightmare? I've used it a fair bit with no issues, 
although TS-DOS with one of the TPDD emulators is more convenient since you run 
it only from the M100 end (once it's installed) and it handles all file types.

There's an article on Bitchin100 about using Hyperterminal; I'd be 
interested to know if it can be improved:

http://bitchin100.com/wiki/index.php?title=Text_File_Transfer_using_Hyperterminal

Note that if you're using TELCOM to transfer files (regardless what's at 
the other end) you will only be able to transfer text files or BASIC programs 
in text format (.DO extension). Machine-language .CO files or tokenized .BA 
BASIC files contain control characters that cause havoc with the transfer.

There are several dedicated transfer clients for the Model T that talk to a 
real or emulated TPDD drive; the most popular are menu-driven TS-DOS 
(preferably in ROM but also available to run in RAM) and CLI Teeny.

Teeny is essentially a stripped-down version of TS-DOS that lets you Load, 
Save and Kill files to/from/on a TPDD or a TPDD emulator; if you have an MS-DOS 
or compatible Windows system then Teeny can install itself from the server.

At the other end the best and most flexible server is John H.'s LaddieAlpha 
(although some of the documentation still refers to its predecessor, 
Laddiecon); if you have a DOS or pre-XP Windows box then there is also Desklink.

BTW, one way around running software like Desklink and the Teeny installer 
that requires 'real' MS-DOS to run on a Linux or late Windows box is to make an 
MS-DOS bootable USB drive; unfortunately last time I checked USB com port 
support in DOS is not easy, cheap or reliable so you'd need a 'real' com port.

These days file transfer between a ModelT and a PC running DOS, Windows, 
Linux or even OS/X is pretty straightforward, with various options to choose 
from; unfortunately many folks still have trouble getting it to work well. Have 
you read the relevant articles on Bitchin100? 

http://bitchin100.com/wiki/index.php?title=Model_T_File_Transfer

Good luck; sorry to hear about your frustration with REX.

Re: [M100] Update on my M100 and REX

Not much of a file manager; it only has three functions: remote Load, Save and 
Kill.

And AFAIK there is only one version for all three Model Ts (M100, T102 and 
T200).

But yes, the 'normal' way to load it is via TEENY.EXE which will only run on a 
PC running DOS or a version of windows prior to XP AFAIK.

  From what I remember Teeny is a file manager,  of just a loader. It is loaded 
onto your Model 100 using the DOS loader from your PC. The DOS loader is often 
called teeny.exe and will only load properly if you follow the connection 
instructions properly.
  It is small and easy to use and there are different versions, one for each of 
the Model-T clones.

James,


I've never used teeny. From what I understand it's a DOS program that must 
have com1-4 to load a client onto the M100. But other than that I don't know

drive. Getting one loaded is not always easy. Obviously REX would be the 
easiest route. I use the Sardine ROM to load a client since it has that

Hi James,

I'll attach a text version of the TEENY client that you 
 can presumably load via minicom.

Start with clean RAM:
(Cold Start, only built-ins in menu, 29638 bytes free (32K)

Connect the cable and download TEENY.DO

Once it's on the M100:

- Invoke BASIC
- F2 (Load) TEENY.DO
- F4 (Run)
- A message 12 Seconds... should appear; wait.
- In response to End Address etc., enter 62959
- At the OK prompt type Clear 0,62212
- F8 (Menu) and you should see a file TEENY.CO
- Select TEENY.CO and you should see 
  C FF.XX (C=KLSQ)

C is the command (Kill Load Save Quit) - Use upper case!
FF.XX is the 6 character file name and extension.
 (Fill with spaces if less than 6 characters).

Assuming it works this far, install John's LaddieAlpha 
 on your Linux box and start it; The only instructions I 
 can find are here:
http://bitchin100.com/wiki/index.php?title=LaddieCon

Maybe John knows of a more recent version.

Full instructions for TEENY.EXE, TEENY.CO as well as
Desklink and various games are in the DL-ARC file that
John mentioned:

Re: [M100] Telnet Client

[Mike Stein]

Sounds interesting for sure.

There are a number of RS-232 bridges out there, both soft- and hard-ware, that 
you might want to look at/play with for ideas/comparison/fun.

As you note, the problem with many of them is buffer overflow due to the 
Model-T's small buffer not being able to handle network latency and the fact 
that data is arriving in packets; some do let you set the size of packets sent 
to the Model-T as low as one character while buffering data received from the 
net until the XOFF is recognized by the sender. Presumably the ones that use 
hardware handshaking would work with John's HTERM.

But as you also note, the issue that seems to keep any of this from actually 
happening every time it's discussed (and it is discussed often ;-) is the lack 
of a Model-T oriented server/BBS...

  The topic of being able to put a Model-T online comes up every now and then. 
I've been toying with the idea of adding a Telnet client to mComm. My thoughts 
were to add the ability to switch to Telnet mode in mComm. When a control key 
is pressed  the TELCOM screen will clear and then ask for a URL to connect to. 
Then, mComm would connect to the remote Telnet server and send all the data to 
the Model-T, doing the all important buffering so that the Model-T serial 
buffer isn't over run before it can send an XOFF.



  On the other end of the wire would need to be a Telnet server that is geared 
towards our little machines. To my knowledge, there are none. One would need to 
be setup. The end result would be a Telnet BBS system geared towards the 40x8 
screen (or 40x16). Or a Linux system with the proper termcap.


  While this is certainly doable, would it be useful?

pay very much for it; how much would you like and where are you?


Thank you so very much for your offer!

You can repair the M102 screens.

Thanks Lee,

Yeah, that's certainly an option and I do have a couple of dead M100s but I was 
kinda hoping to repair those one day instead of stripping them for parts.

Definitely something to keep in mind though; thanks again!

  I've grafted a 100 screen into a 102, you just have to solder the wires to 
the flex cable traces.   That is, if you have a m100 screen laying around.

Re: [M100] USB "juice pack"

Damn; they won't ship to Canada.

You could even top up your bike tires, but you'd still need what started all 
this, the USB<->M100 cable.

For $2.00 you could use this version (although you could of course just keep an 
AA four-pack in your pocket...):

That's one of my 'frontlight's in the foreground, optionally powered by BarCode

  As an aside, I attach here a plot of battery voltage vs. time. This was

That is characteristic of NiMH batteries. Alkalines have a more gradual slope

I just tested the power requirements of my 102. With the battery 
connectors connected to a bench supply at 5 volts, it draws a very consistent 
65mA. I was expecting the current to vary slightly with CPU or screen activity 
but it does not. I'm so used to CPU idle states which, of course, the 8085 does 
not use :)


I have one of these kicking around at home

  But then I thought, since we have the extra weight anyway, what if the M100

Re: [M100] Full Null Modem Cable Cottage Industry?

Presumably because PC com ports are also male and whatever you would have 
plugged into that port or the USB converter replacing it would therefore have a 
female connector; female<->female adapters are cheap. A female 25pin RS-232 
port as in the M100 is relatively unusual, and is/was a parallel printer port

  Is there a reason why a null-modem configuration with a 9-pin female isn't

A nice printer; I've got three of them, never a problem.

Doesn't sound good; not likely a configuration issue.

Is the cartridge properly inserted? Does the carriage move freely?

  Hello – this is my first post, though I follow with interest.  Greetings and 
Happy New Year 2016 to my fellow Model 100 enthusiasts worldwide!

   

  I recently purchased a Canon BJ-10e inkjet printer to use with my M100, but 
after a great deal of experimentation, I haven’t been able to get the printer 
to work.  (Error light is pretty much perpetually on.  Essentially does nothing 
that the manual suggests the printer should do, including self-tests.)  This is 
confusing, since the BJ-10 seems like one of the older but still “relatively” 
modern printers that folks on the list have called out as being well-suited to 
the M100.  I’m using an original Radio Shack printer cable for the M100, so I 
think I can rule out a connecting cable error.  I even bought a replacement 
rechargeable battery for the printer, thinking that might be the issue, to no 
avail.  I’m hoping someone with experience configuring this printer can help me 
out.  Do the printer’s DIP switches need to be set in any particular manner?  
Is there some other “trick” or even just a common failure mode?  I’m beginning 
to think that I was sold a piece of junk with a fried logic board.  I want to 
exhaust options before throwing the printer away in frustration.

   

  Best wishes and thanks,

  Anthony

 NADSBox is basically not being sold any more.  I have maybe 13

 It would be fun to know the modern answer, too. I've tried various cable
 converters from serial to USB, without much luck. The last time I made
 it work flawlessly was with my Mac SE, using the original Mac pin
 printer cable (which was a null modem cable) back in my newspaper days.
 The Mac side used Mock Terminal, which we also used to operate our
 modems.

 My most recent attempt, some years ago, also successful, was with a
 serial to USB cable and some version of Z-Term, but on a Mac OS 9

 emulator on OS X I believe is different than the Terminal software
 resident on the new Macs. If it can be used as a Comm terminal, I never
 understood how.

Alternatively, unless you need 6V somewhere else (or are in Canada ;-), 5V is 
quite sufficient for the M100 and straight-through cables are cheap; trivial to 
reverse the polarity:
e.g:

If you need 6V (or more) there are boost converters, although you'll have to 
supply the cable and I haven't seen any nicely enclosed like the MyVolts unit:

I think the 28C256 SOIC board is essentially the same as ROMBO/MOMBO. Adam 
("FigTroniX") made it from me showing him pictures of the ROMBO/MOMBO. Ideally 
I'd like to get a removable eeprom option working, and get onto a package that 
will be more readily available longer than soic, but until then the soic board 
works and you can still buy new soic 28c256 from Mouser at least today.



I think the MOMBOs were indeed similar to what you're talking about, but the 
earlier ROMBOs used a funky dual-sided flexible PCB that wrapped around the .6 
DIP EPROM (or the RAM in this picture of a RAM option ROM):

There is no functional difference on that one aspect by itself.
Ideally I want to keep working on this to get to where you don't have to 
desolder the original socket. It's just like that now because I had to choose 
one or the other.
Mostly, it's not a contest, and it doesn't matter how cool one thing is, other

Absolutely!

I just wanted to clarify a few things for myself.

If I thought that there was enough interest I'd also look into the feasibility

Re: [M100] Schematic needed

[Mike Stein]

Interesting...

What are the serial numbers of the two machines? Most of the 'old' M100s use a 
board labelled PLX110CH1X; is yours a model meant for a market other than North 
America by any chance?

Similarly, most of the T102s use a board labelled PLX144FH1X so again, I wonder 
where yours came from and/or how old it is.

But in any case there shouldn't be an issue around M18. In both the m100 and 
the 102 C17 and C18 are padding caps for the crystal and go between pins 12 & 
13 to ground respectively, and C19 is merely a bypass cap from Vb to ground; I 
can't see any reason why that would change.

There are minor differences among the different M100s and the 102, mostly 
related to RAM and ROM chip and connector pinouts, but nothing around M18 that 
I can see (or imagine).

See Fig. 4-16 of the M100 Service Manual or Fig. 2-12 of the 102 Tech reference.

Something to have a look at and see if there are any buffer size/timeout

While the timestamps may be accurate, the listing doesn't actually show 
proper protocol packet interleaving between the two ports.  The 2nd COM5 block 
shows 23 "ZZ1" protocol packet headers with no interleaved ACK packets, and the 
following COM6 block shows 23 ACK packets with no interleaved "ZZ1" protocol 
packet headers.  It is easy enough to figure out that these two are actually 
interleaved in time, but just wanted to point this out to anyone looking

  Hi All,

  I have captured the communications between the Model 100 and the TPDD2 
during the creation of a TPDD2 boot disk.

  The capture file is at 
http://trs80stuff.net/tpdd/tpdd2-boot-disk-create.txt

  Com5 is Model 100 -> TPDD2

  Com6 is TPDD2 -> Model 100

  Time stamps are accurate as they are recorded on the same PC.

  The capture is the writing to the TPDD2. The reading of the original boot 
disk process is not required as the necessary data to write a new disk is in 
the capture. If we can convert it to code (a project for when I am a little 
less busy), it will need to be assumed that the disk has already been formatted.

  As the sequencing and timing is all in place, the right sort of Python 
script could read the capture file directly and generate the appropriate 
commands/data and know what to expect back from the TPDD2 and in what time 
frames.

  Enjoy!

Hi James,

Yup, a 9 pin to 25 pin F-F adapter is what you need.

Originally you would use a program called LAPDOS to format, copy files to/from 
a PC etc., but AFAIK it does not play well with modern versions of Windows or 
Linux/Mac OS's.:

http://www.club100.org/library/doc/lapdos.html

Also the later version LAPDOS II with a number of added features:

http://www.club100.org/library/doc/lapdosii.html

But recently a fellow member, Gary Hammond, wrote a modern version that runs on 
a wider range of systems and from reports so far seems to work quite well.

Of course!

It's good to have multiple ways particularly with Rex temporarily out of stock. 

I tend to be biased towards Rex because Steve it adds so much utility while 
Steve has keep the price artificially low.

Absolutely!

If you want to use Option ROM images or play with modifying an option or system 
image then REX is a terrific product and extremely reasonably priced, 
especially considering the finicky assembly required; one of the reasons we 
never continued with the ExtRAM M100ROM Combo version was that REX gives 
you so much more for so little more money.

But for someone like me who isn't particularly interested in Option ROMs but 
only wants to fix a few System ROM issues like Y2K etc. and wants to add file 
transfer and disk access to the built-in functions the M100(Combo)ROM is all I 
need.

Nevertheless I do also have an ExtRAM and a REX for tinkering...

Re: [M100] Adapter Board

[Mike Stein]

Hi Brian,

I think that the space at one end would be enough for a diode or even a small 
jumper; as a matter of fact one of the jumper positions on the M100ROM board is 
for (re)programming. You'd still need an adapter of course.

But I don't think I'd bother unless I had a pile of 27C256s to get rid of; the 
FigTronix EEPROM version of the MOMBO looks pretty good if you actually want 
'real' option ROMs to plug in and out.

  Crap I'm sorry Mike!

  But the question was about an option rom not the main rom. A dip28 chip just 
about fills all available volume in the option rom socket. If you need to add 
anything else to the board, it will be difficult. There is a little room on the 
edge, and there is about 1/10" of height across the bottom. Can you make a 
27C256 both usable and re-programmable within those constraints? Would it need 
a jumper and resistor like 28C256 does?

  As for rex, now that Stephen has put a version of rex up on osh park I plan 
to try to build one and we'll see. I've already ordered a set.

  If it costs more in parts, that's a potential reason.

  If it's more difficult to build, then that is a potential reason. It was easy 
to do the soic option rom, and the through-hole plcc socket main rom, and your 
own dip28 main rom. The qfp legs are finer than soic, but still look doable, 
but that tsop chip...well we'll see, maybe it's fine.

  If it requires special software or hardware to program the cpld, that is a 
protential reason. I can program an eprom using small purely open source 
software and $30 hardware. For the fpga in the MISE, I got a ByteBlaster for 
$25 and the programming software was free, but it was a large download of 
proprietary software, and was not easy to get working on the linux netbook I 
like to use for stuff like this where possible. I don't know yet what it takes 
to program the cpld on the rex, but I'm guessing it will be doable and within 
reason like those examples.

  If there is any software incompatibility, that is a potential reason.

  If it conflicts with the option rom socket, then that is a potential reason.

  A 27C256 is problematical in the option rom socket because you can't

The 28C256 board can do it because the chip is SOIC package and there is 
physically room for the parts.
  There is no such thing as a SOIC 27C256, or at least not an erasable one. 
Burning and soldering a chip as a one-way trip is not really hobbyist friendly. 
You risk wasting $6 chips and having to de-solder, clean, and resolder chips on 
the board for every mistake or testing another rom.
  It's different if you're producing 100 copies of the same thing to sell. 
You don't care about re-writing then. But in that case you have the resources 
to just whip up your own new board any time you want. A few different similar 
board designs are public that you can download and copy, and even the cad 
software is free (kicad). Edit and upload to osh park and order as set for $6.
  But I suggest just use the SOIC v2.0 28C256 board. And get the option rom 
programming adapter v2 at the same time. And some singlenrow machined round pin 
headers for the programming adapter.
  Or use the m100 board (Stephen's, not FigTroniX) and use the option rom 
feature on that. It goes in the main rom socket inside, not in the option rom 
socket, and it can provide both a main and option rom in one uv-erasable 28 pin

  that looks exactly like the documentation from the Marty Goodman doc. Does it

  I think in that design the resistors are superfluous. The reason is that 
there's only 110ohms of resistance at the TPDD signal outputs, which is a lot 
less than 22k, so most of the drop will be across the 22k to ground. If we use 
the rule-of-thumb for a diode of 0.7V drop at 0V input, you will end up with 
about -1.8V to the receiver input in the computer. That is low enough to 
register as a '0'... according to my calcs at the receiver inputs about 0V 
+/-0.5V swing would be the dead zone. 


  Good idea for using the CDROM audio cables. I was thinking I'd use a 
pre-molded RS232 cable and a header cut down, and encase the guts in a glob of 
hot glue at that end for the housing. :)

Retrochallenge 2016/01: Maze War for Olivetti M10 and NEC PC-8201A


"I recently acquired two 1983 portable computers, namely an Olivetti M10 
and a NEC PC-8201A. Both are siblings of the Kyocera KC-85 platform, comprising 
— in alphabetical order — Kyocera's own Kyotronic 85, the NEC PC-8201(A), the 
Olivetti M10, and, last but not least, the TRS-80 Model 100, with about 6 
million sold the most popular of all. (1984 saw the addition of two further 
models featuring more initial RAM and refined ROMs, the NEC PC-8300 and the 
TRS-80 Model 102.)


"These computers came with a nice version of Microsoft BASIC v.1, a LCD 
display featuring 8 rows at 40 characters and a graphics resolution of 240 × 64 
pixels, and a nice imple­men­tation of serial communications via RS-232C (the 
NEC PC-8201 adds two more SIO interfaces). So we should be able to network the 
machines and have a decent game of Maze War running on them, preferably written 
as a single cross-platform program."

Re: [M100] M100 ROM still available?

[Mike Stein]

> Does anyone know if the updated M100 ROM is still available?

Short answer: yes.

Long answer:

1 - There are two common physically incompatible versions of the ROM and 
motherboard:

- If your M100 is newer than 01/01/84 (serial no. starts with '4') then it will 
probably use a JEDEC standard 27C256 type; those are a drop-in replacement and 
I could send you one (programmed) for $3.00 plus postage from Toronto.

- If your M100 is older than around September '83 (< 309xx) then it will 
probably use a non-standard ROM and you will need an adapter, available for 
$15.00 including the EPROM (unless you're comfortable building your own; at 
least one member has done so).

In any case but especially if the serial no. is between 309 and 401 you should 
probably open it up and confirm the part number of the ROM and the motherboard 
(Old: PLX110CH1X, New: PLX110EH1X, assuming we're talking about the North 
American version).

- If you do need/choose the adapter then you get an additional bonus: an option 
ROM of your choice (usually TS-DOS) can be integrated into the same chip at no 
extra cost; this also applies to the 'new' version ROM if using the adapter.

2 - As to the actual contents of the replacement EPROM, the main reason for an 
update is the Y2K of course; there is also a minor correction to one of the 
math constants and some people prefer the 102's pi symbol to the M100's 
vertical bar. I personally also prefer a com default value of 19,200 baud 
instead of the 300bd modem which I almost never use, and some folks like to 
replace the MS copyright with a message of their own as in Virtual T. Anything 
trivial can be modified.

Re: [M100] ROM Available

[Mike Stein]

Re: [M100] ROM AvailableHi Georg,

Thanks for the plug; you beat me to it. When I've mentioned this adapter 
there's usually been little or no interest so it's gratifying to read that 
someone else has actually built one and is happy with it.

I haven't tried it but I see no reason why it would not also work in the option 
ROM socket with a suitable spacer; in fact that might also give you the option 
of two (or even more) option ROM images.

Regarding the pins, yes, the ones I used seem to have become scarce and/or 
expensive; however, you could probably use pins extracted from a suitable IC 
socket with the tops cut off, or even just short pieces of wire.

And thanks to Steve Adolph for his help in getting the original boards made and 
his excellent writeup on Bitchin100! Unfortunately since he was working with an 
old schematic the option jumpers are not shown or explained; they select a '256 
or '512 ROM and also allow (re)programming if it's configured for a 'new' M100 
(or you make a 'reverse' adapter). 

Perhaps it's worth mentioning again that when it comes to the pinout of the 
System ROM there are two versions of the M100: the original version used a chip 
with a slightly non-standard pinout, similar to the option ROM; some time late 
in 1983 (serial numbers starting with 311, 312 or 4) they changed to a JEDEC 
standard 27C256. See WhatVersionM100.pdf in Steve Adolph's personal library on 
Club100.

Thanks again,

mike

Re: [M100] ROM Available

[Mike Stein]

Re: [M100] ROM AvailableHi Gary,

Nice boards! A little different from mine; they both (optionally in my case) 
convert the non-standard pinout to the JEDEC 27Cxxx standard, but while yours 
is meant to provide alternate system and option ROM images mine was intended to 
provide an option ROM without the PITA of using the option ROM socket.

I don't like to use machined pins because they tend to distort the socket, so 
the pins I used are flat and allowed flush-mounting; I also didn't socket the 
EPROM so clearance wasn't an issue. Obviously if you use the option ROM socket 
instead of removing it you will have problems unless you use a board with a 
smaller OTP ROM that actually sits inside the Molex socket.

Incidentally, there is such a board on OSH Park that uses a 32-pin PLCC 28x256 
EEPROM, courtesy of Adam, KD5VMF; it only remaps the pins but could probably 
easily be modified to fit inside the Molex socket and also provide alternate 
images:

  Hi All,
  I wish I had known about the other ROM board earlier. I ended designing my 
own board which I have been using for both the M100 ROM and the option socket. 
Photos of my board are at http://trs80stuff.net/m100-option-rom/
  For the M100 ROM, I use an 256k OTP with the M102 ROM image modified for Y2K.
  For the option socket I have removed the old style molex socket and replaced 
with my adapter board.
  Some observations:
a.. I can’t use a an IC socket on both the M100 board and the option ROM 
board at the same time without hitting height problems. It is ok for the option 
ROM providing you don’t want to put the cover back on.
b.. For the ROM socket I solder the pins to the adapter board the clip the 
top side pins as close as possible to the PCB. I then solder in the programmed 
OTP. The keyboard does touch the top of the OTP however it alls goes back to 
gather with no visible bulge in the keyboard.
c.. For the option ROM socket I do it the other way, i.e., I solder the 
adapter board to the M100 main board and use a socket on the adapter board. I 
have found that trimming the legs of the EPROM slightly gives me just enough 
height to put the cover back on.
  I have not been able to find any really low profile pins. The ones I got add 
about an extra 4mm to the board height. If any one can point me at some low 
profile pins it would be appreciated.
  Cheers,

Re: [M100] Could you use a USB portable flash drive as an alternative device to stores files on a Model 100 ?

[Mike Stein]

Aside from the cheap SBCs like the Pi0 and CHIP there are a number of dedicated 
RS-232 or parallel to USB adapters that are _almost_ ready to go, just needing 
a level shifter/clamp and some simple software.

Some examples:

  I was wondering if you could use any USB Flash drive to save files. Maybe 
have some software written for it so the Model 100 would understand it. 



  I heard of the NADSBox and Raspberry Pi. But the NADSBox is expensive and I 
am not sure if it is available anymore.


  As for Raspberri Pi. It is $35 dollars. I have even seen one for $15. Even a 
CHEAP one for $5. But I am not a very technical person or software programmer 
or hardware engineer. I am just a basic user and owner of a TRS 80 Model 100.



  Any suggestions or opinions that I can get.

Re: [M100] Greetings and some questions

[Mike Stein]

Hi Gary,

It'd be interesting to see more details about your adapter board. There are a 
couple of boards available that replace the system ROM with a JEDEC standard 
256 or 512K EPROM that lets you update Y2K etc. and also add an option ROM in 
the upper half; they just plug into an M100 but if one is willing to replace 
the option ROM socket I suppose they could also be used as yours is. Also, a 
number of people did the multi-image ROM trick with systems like the NEC etc. 
that already used a standard socket instead of the Molex.

AFAIK there are no known issues replacing the M100 ROM with the 102 version; 
IIRC the 102 mainly corrects a minor error in the 100's trig constants, 
replaces the vertical bar with a Pi symbol and fixes an issue with the year-end 
date (although it's still not quite correct).

Yes, corrosion or broken diodes and traces are fairly common keyboard problems, 
from corrosive liquids being spilled or something heavy being placed on it 
which flexes it over the little central support peg; leaking NiCd backup 
batteries can also cause problems.

If by chance you have another 5 1/4 DD floppy drive or a 3 1/2 drive with the 
appropriate adapters then I'd try replacing it to see if the problem is in the 
drive or elsewhere; barring that, it never hurts to clean the head and clean 
and lube the support rails. A PC that can use a 5 1/4 DD drive would also be 
handy to test the drive.

Regarding the Club100 store, it is really a much smaller enterprise than it was 
when it was Rick's baby, although the web site doesn't really reflect that. 
Ken, the current 'manager', checks in here regularly and will no doubt be glad 
to help if he can; unfortunately he has had some personal distractions so 
please be patient.

Good luck, and welcome!

  Hi All,
  I have recently joined the list and am glad to see there is still a fair bit 
of stuff going on.
  I am a collector of TRS-80 computers of which I have some Model 100s, 102’s 
and a 200, DVI, TPDD and a TPDD2 amongst the other TRS-80 stuff. I have 
repaired the non-working ones, and the ones which are not collector quality, I 
have modified with a small option ROM adapter board I got made up to get them 
into a more useable state. Some of the mods to date include:
a.. Replacing the non-standard molex 28 pin IC carrier with my adapter 
board which allows either a 256K or 512K standard pin out eprom to be used. I 
can use a jumper to switch between 2 ROM images in the 512K version. Not as 
flash as a rex (ha pun intended!) but good enough to try out the option ROMs. 
b.. Using the same ROM adapter to update model 100’s with the LH535618 ROM 
with a model 102 ROM modified with the Y2K fix. Is there any known issues using 
the 102 ROM in the 100? So far it seems ok but it has not been extensively 
tested.
  In repairing the faulty models, I have come across 2 instances where tracks 
on the top side of the PCB where corroded. I one case it was an open circuit 
trace that prevented the reset circuit working. In the other case, it was a 
high impedence intermittent trace that caused the LCD –5v rail to fluctuate 
resulting in random dimming of the LCD display. Is it normal to come across 
these types of faults? Bear in mind that there was no other evidence of 
corrosion and there was no sign of battery leakage.
  On another M100, there were a number of physically broken diodes on the 
keyboard PCB and a number of keys that needed desoldering, disassembling and 
cleaning. Did manage to get the keyboard running in the end.
  The DVI I have appears to have an issue with the 5.25” drive. It reads the 
disk fine, but any attempts to write to the disk seems to make the disk 
unreadable. Does anyone have any ideas or tips for fixing this?
  And of course, the last question is while I get great satisfaction in 
breathing life back into these, does anyone have some good working uses that 
they put their portables to so as to earn their keep!?
  Cheers,
  Gary
  P.s. Apologies for the long first post.
  P.p.s. If the person who looks after the the old club100 shop lurks around 
here, I tried to order some stuff but didn’t get a reply.

As a matter of fact when I was playing with the socket interface I was using

although you and I did discuss it at the time.

Another tool to keep in mind is a keyboard/mouse emulator such as AutoHotKey; 
it's surprisingly powerful and flexible and can often come in handy for stuff

That's what I said, that it's not actually necessary to convert; just rename 
them (if they truly are plaintext .BA files).

Yes, I guess I could have made it clearer that instead of converting the files 
it was instead decided to modify the latest TS-DOS server side (LaddieAlpha) to 
avoid the issue, but I thought the NADSBox also does that; am I mistaken?

IIRC it took about five minutes to convert all the files in the BBS libraries 
section and another 15 minutes or so to convert them back and check for 
discrepancies. ISTR that Bob Pigford also helped out at the time with resolving 
the odd discrepancy.

Not really an issue in the libraries but certainly something to look out for 
elsewhere.

BTW, it is sometimes necessary to rename the file itself, e.g. when there 
already is a .DO file containing documentation; another issue is different 
versions named .100 and .200 for the respective models.

Probably ;-)

First of all it isn't really necessary to convert them anyway, as long as you 
rename the (plaintext!) .BA files to .DO; note that some .BA files really are 
tokenized .BA files and should be left alone.

The advantage of .BA files is that they are smaller and load faster, the 
disadvantage is that you can no longer read them in a text editor or transfer 
them with a text-only program (e.g. TELCOM).

Second, if you do want to convert them manually it will be much faster if you 
use the most excellent VT emulator and do it on a (presumably much faster) PC, 
without the back and forth TS-DOS transfer.

Note that the ModelT will load a .DO file by default if it does not find a .BA 
file, and the save default is .BA. Thus, LOAD "FILENM, SAVE "FILENM (without 
extensions) is all you need.

Third, there are standalone programs to convert .DO >> .BA (and .BA >> .DO) on 
a (DOS/WIN) PC, either individually or in batch mode. One such program is 
ENTOKE(B).EXE in my member upload folder on Club100; IIRC it has a little bug 
that affects around one in 50 programs, but since at the time it was decided 
that it would be better instead to modify the TS-DOS servers to handle the 
issue I never took the time to fix it. I'll leave it for you ;-)

Finally, which files are you converting? At one time it was planned to convert 
all the files on the Club100 site and most of the files were indeed converted; 
unfortunately the fellow who had volunteered to update the web site never 
followed through.

Have fun!

A nice little machine actually, generally sells for $10-$20 or even less (note 
that there are also various other versions):

8x80 display (not lit); cursor-key GUI menus.
4xAA batteries, CR2032 backup.
RAM file system, similar to model T.
~150K RAM.
Parallel, Serial and IR ports.
Pretty good keyboard; top row doubles as dual-function function keys.

Built-in apps:
Word processor with the usual features incl. sub & superscript
Spell checker, Thesaurus & Dictionary
Terminal program with Xmodem and standard text transfer, h/w or XON/XOFF, 19200 
max
Typin' Time typing tutor
Calendar

  1. No interval will exceed 24 hours.
  2. One-second resolution is adequate.

  To be a little more explicit, the object is to record the time of  "ON"/"OFF" 
events and their duration occurring over the course of several days with 
several events occurring each day. The real-time sequence will be:


  "ON" - Record current time
  "OFF" - Record current time and elapsed time since previous "ON"
  "ON"  Record current time and elapsed time since last "OFF"
  .

  etc.

  The only real issue is the conversion of the character-stringed TIME$ to

Re: [M100] Mike (not Mark ;-) Stein's ROM Board

Hi Bill,

Not sure what you mean by handshaking on the port or the null modem; 
handshaking is usually selected and handled by the software at each end. The 
port and cable are essentially transparent; they don't always pass on the 
hardware handshake signals but that shouldn't matter for TS-DOS.

TS-DOS and its various servers do their own ACK/NAK kind of handshaking so 
anything else should probably be disabled.

What exactly do you have between the M100 and Desklink that gives you 
handshaking options?

I'm just surprised that the utility disk files aren't already out there

  Hi All,



  So here’s something different…a tool for talking to a real TPDD from a 
PC. This is the opposite of most of the discussion here on the list.

  I have just finished off the first version of a TPDD command line tool I 
have written. 

  The problem:

  The problem I wanted to solve was find an easy way to transfer to a TPDD 
disk, files to and from my PC. It was getting laborious transferring files one 
at a time via telcom or basic over the serial port from the PC, then switching 
over to the TPDD and writing the files back. Even using TSDOS and loading up 
the max amount of programs in the M100’s RAM then transferring them as a group 
via TSDOS is still a time consuming process.

  The solution:

  I can now connect my TPDD or TPDD2 to my PC, which can be Windows, Linux 
or Mac. I then use the command line tool (TpddTool.py) to perform disk based 
commands using familiar command line syntax. The commands include:

  -  cp myfile.do 0:myfile.do

  -  cp 1:myprog.ba myprog.ba

  -  rm 0:file1.co

  -  cat 1:myfile.do

  -  mv 0:wrong.do 0:right.do

  -  format

  -  status

  -  dir 1:

  and my favourite:

  -  cpd filedir 0: (this is used to copy a folder of files to the 
TPDD or copy the bank of a TPDD to a folder all in one go!

  The commands also take DOS equivalents i.e., copy, ren, del, type and 
copydir.



  I have tested the software using a TPDD and a TPDD2 with real coms ports 
and USB com port on Wndows 10, CentOS 6 and 7 and Mac OSX (El Capitan). A 
fortuitous side effect of writing a test suite for the API is that I now have a 
great tool for testing a physical TPDD!



  The tool is written in Python and is available with documentation from 
http://trs80stuff.net/tpdd/. The reason for Python was its cross platform 
compatibility, source code that can be easily read and re-used, and that it 
fitted in with some up-skilling I wanted to do for work with respect to auto 
documenting code and the nose test framework.



  Future ideas I have in mind are:

  -  Set up and test in on the Raspberry Pi.

  -  A GUI for drag and drop functionality.

  -  Implementation of the sector based commands so that a true 
disk copy can be performed. It would be a good way to make disk images.

  -  Create yet another drive simulator to work in the opposite 
direction. It would be good on a Raspberry Pi.

  Please post any feedback to myself directly or via the list.



  Enjoy!

Re: [M100] New command line tool for TPDD and TPDD2

It's been a while since this was discussed but my recollection is that the disk 
just has 'normal' files on it. There is of course a bootstrap *process*, which 
is pretty well documented here (for example):

  I thought the original disk did have a special bootstrap process. If it

Excellent!

I think LAPDOS would have saved you some time and frustration but of course 
like most of the 'classics' it needs a real or emulated MS-DOS system; I'm sure 
that the TPDD owners will appreciate something that runs on a modern system.

  Yes, you can do things like this from the BASIC prompt:


  Load "COM:98N1E"


  Then just initiate an ASCII upload of a non-tokenized .BA file (plain

can directly load into basic.  Crazy, eh?






And LEGACY is so large it is the only way to load it. You can't load it to 
ram first as a DO and then load into basic. You either have to tokenize it 
first and load it as a binary BA or you have to load it straight into BASIC.

Option 1: Buy a REX module. I'm not sure whether they're still available 
through Club100 or you order them direct from Steve these days; I'm sure Ken or 
Steve will log in and clarify.

Option 2: If you just want to replace the System ROM in a *NEW* M100 (or don't 
mind unsoldering the original ROM in a T102) then all you need is a 27C256 like 
the one below at jameco.

Option 3: If you want to replace the System ROM in an *OLD* M100 and/or add an 
Option ROM to an old or new M100 then you'll need an adapter. If you're only 
replacing the System ROM then a 27C256 is all you need; if you're adding an 
Option ROM then you'll need a 27C512.

If you're up to assembling the adapter yourself then you can buy 6 bare boards 
for $20 at Oshpark:
https://www.oshpark.com/shared_projects/Kil9S1ya

You might want to read:

You might also want to read the thread about Bill Nobel recently doing what you 
want to do in the Bitchin100 archive, March and April; maybe you and he can 
even get together off-list.

Maybe he has a spare board that he can sell you; if not, I could probably come

  Hi Steve,

  Where to begin...

  First of all, you're talking about two different and separate ROMs and their 
sockets, the System ROM which runs the computer and provides the various 
built-in applications, and an Option ROM which, as the name suggests, adds one 
or more optional programs or features. They are both 28-pin 32KB (256Kb) chips, 
so your 32-pin 128KB 27C010 chips will not fit without major adaptation.

  As you (re)discovered regarding North American models, early M100s (prior to 
late 1983) used a non-standard pinout while later M100s and the T102, T200 etc. 
used standard 27C256-compatible ROMs; the change seems to have been made 
somewhere between serial numbers 309xx and 401xx.

  If you want to replace an early M100 System ROM you will have to make or buy 
an adapter; a fellow list member just built some using this board:
  https://www.oshpark.com/shared_projects/Kil9S1ya
  Replacing a later model M100 System ROM is just a matter of plugging it in, 
but in the T102 it is soldered to the board and would require unsoldering the 
original ROM.

  The Option ROMs use a completely different socket arrangement, a Molex IC 
'carrier' with non-standard pinout but you can use the adapter above which lets 
you combine the System and Option ROM in one chip that plugs into the System 
ROM socket (old or new). At one time there was an adapter available from 
several sources that would let you put an OTP (not re-programmable) EPROM into 
the option ROM socket but they seem to not be available any longer.

  Most people use Steve Adolph's REX module, which lets you put several 
different ROM images into one flash memory and I believe the later versions 
also permit changing the System ROM; see:
  http://bitchin100.com/wiki/index.php?title=Rex

  Another very useful add-on is/was the NADSbox but I believe they're no longer 
available unless you find a used one; a newer version may or may not become 
available in the future.

  Can't really give you a step-by-step since I don't know exactly what you want 
to do with/to what.

  Good luck!

Re: [M100] Telnet BBS

[Mike Stein]

Hi John,

If you have a computer connected to the Internet that also has a serial port 
there are programs that let the M100 think it's talking to an old-skool modem 
while the PC translates things to Telnet on the 'Net. There has also been a lot 
of progress made on using a smartphone as a 'modem' to connect the M100 to the 
net, and finally there are also hardware devices specifically for connecting 
RS-232 devices like the M100 to the internet.

Maybe some other folks have some more ideas...

  Back in 1985 to 1995. I used my TRS 80 Model 100 to call up local BBS here in 
Colorado Springs, CO. But most of these BBS in my city no longer exist. Since 
1995. I do not know how to call TELNET or any BBS outside the 80906 zip code. I 
wish there was a FREE toll free 800 or 888 number. So I can use my home

Re: [M100] Mdeol 100 FACEBOOK group

[Mike Stein]

Let me try to salvage something from this 'discussion'; I certainly didn't mean 
to start up a love/hate FB flamewar, I only wanted to say to William James the 
OP that it's a shame that he didn't (also?) put his no doubt interesting stuff 
on a site that everyone could access, not just FB members. 

I would have liked to see his stuff but like many others unless I *really need* 
some information I will usually on principle not follow up anything that 
requires that I sign up to join yet another group or list, wait for approval 
etc., only in order to access some bit of info or look at some pictures (and 
probably add to the spam already in my inbox).

FWIW I am a member of several Google groups that interest me, and in reply to 
Shaun's post, no, he's not the only person alive who uses Google+; I also do 
(although I haven't quite figured it all out yet).

Regarding Bill's comment that "[Facebook has] the ability to have photos and 
videos posted where many of the lists don’t allow or have the capability of 
it": true enough.

But my point was that while mail lists are not the place for blogs, videos or 
more than an occasional illustration, there are many places other than FB for 
that sort of thing (which you can then link to on the mail list as William did).

So, the point of this post (finally ;-) is to ask what free sites you folks use 
and recommend for hosting illustrated blogs or just pictures and videos that 
*everyone* can access and enjoy?

Bitchin100 of course
Google Drive
Wordpress
Picasa

Ah, OK, and thanks for your reply, Ken; that's what I thought. 

I guess at this point when we're talking about 'ROM' versions of TS-DOS we're 
usually actually talking about (E)EPROMS, even back when Rick was selling them 
(although I think his were OTP versions so they might as well be ROMs).

And then there's ExtRAM and XR4; all this nitpicking just to say that, 
excellent product that Steve's REX is, it's not the only way to have TS-DOS (or 
any option ROM) 'in ROM', as it were...

So yes, like Bill N I'd also be interested in that 'fix' if you get the

Thanks, Ron:

Looks like I did indeed mis-remember that they're 'ordinary' diskettes.

So, while there are several ways to *copy* an existing diskette, is there any 
way to create a 'boot' diskette from scratch, i.e. an image or set of files? 

Is it even necessary? AFAIK you can install FLOPPY(.CO) (and TS-DOS) manually; 
is that not enough?

Hello Mike:

As I recall, the "Utility Diskette" of the TPDD and the "Utility Diskette"
of the TPDD2 are formatted as boot diskettes, rather than as data diskettes.
Their boot records, that originate as sector 0 and have a special
lead-character in their file name, house their disk service: Floppy.CO (a
HIMEM system) in the case of the TPDD, and FLOPPY (a MAXRAM system) in the
case of the TPDD2.

There are a few ordinary files included on each "Utility Diskette" which can
simply be inloaded.  But the disk drive boot procedure is what inloads and
installs the disk service.

At least that is my recollection.

it be a problem to copy them to a PC and make them available, and then

Hi All,

So here's something different.a tool for talking to a real TPDD from a PC.
This is the opposite of most of the discussion here on the list.
I have just finished off the first version of a TPDD command line tool I
have written. 
The problem:
The problem I wanted to solve was find an easy way to transfer to a TPDD
disk, files to and from my PC. It was getting laborious transferring files
one at a time via telcom or basic over the serial port from the PC, then
switching over to the TPDD and writing the files back. Even using TSDOS and
loading up the max amount of programs in the M100's RAM then transferring
them as a group via TSDOS is still a time consuming process.
The solution:
I can now connect my TPDD or TPDD2 to my PC, which can be Windows, Linux or
Mac. I then use the command line tool (TpddTool.py) to perform disk based
commands using familiar command line syntax. The commands include:
- cp myfile.do 0:myfile.do
- cp 1:myprog.ba myprog.ba
- rm 0:file1.co
- cat 1:myfile.do
- mv 0:wrong.do 0:right.do
- format
- status
- dir 1:
and my favourite:
- cpd filedir 0: (this is used to copy a folder of files to the
TPDD or copy the bank of a TPDD to a folder all in one go!
The commands also take DOS equivalents i.e., copy, ren, del, type and
copydir.

I have tested the software using a TPDD and a TPDD2 with real coms ports and
USB com port on Wndows 10, CentOS 6 and 7 and Mac OSX (El Capitan). A
fortuitous side effect of writing a test suite for the API is that I now

Re: [M100] Parts for an NEC PC-8300

[Mike Stein]

Looks like it might be the same idea as 64Kb ROMs vs. EPROMS; most of the ROMs 
used in arcade machines, lots of Commodore models and even the IBM PC were 24 
pins whereas the 'normal' 64Kb EPROMs were 28 pins with the exception of one 
Motorola part; a simple adapter took care of the problem.

Anybody know how to get in touch with Gary Weber? He'd know, and also be able 
to make a stock ROM.

Looks that way; what confused me was that there are images out there (even with 
the Y2K adjustment) that are labelled 27C512.

If you can send me or point me to an image of that ROM I can probably burn an

  I have recieved the Molex sockets. 134 sockets. Anyone wants one, or a few, 
just tell me. I'll give most of them away for the cost of mailing. I only paid 
$30 for the lot.

  They are useful for 2 things:


  * Programming a 27C256 that's already in a carrier. This is for Model 600.
  https://goo.gl/photos/rxtctgxYvvrsjiDR6


  * Programming a Figtronix 28C256 module. This is for Model 100/102/200, and 
requires the complimentary Figtronix "programming adapter". (You install pin 
headers on one side of the board, to go into the programmer, and install the 
socket on the other side of the board. The board just un-scrambles the pinout 
from the module back to a 28C256 pinout.)
  https://oshpark.com/shared_projects/LfdyAK6a
  https://oshpark.com/shared_projects/4vDl1ecB
  https://goo.gl/photos/XSQrBshVY44xbp687


  You can program the 100/102/200 module other ways. If you happen to have 
either a dip28 or a soic28 test clip, and 28 jumper wires. But it's not as 
convenient to set up the wires, and the test clip alone costs $30 or more. But 
if you're building the module, then you already have everything to build the 
programming adapter even easier.

  One thing, at this moment, the programming adapter design up on oshpark 
currently has holes that are too small for the pins on the Molex socket. Until 
the design is updated, you can solder a regular dip28 socket to the board 
instead of the special Molex socket, and then stick the Molex socket into the 
regular socket.


  Another thing: You might not need any special programming adapter or test 
clip ultimately.
  There is a different option rom module that isn't verified yet, but it uses a 
low profile plcc socket instead of a soldered soic.
  https://oshpark.com/shared_projects/iY7EaSqU



  If that one works out, then you would only need the regular plcc adapter that 
you can get in a kit along with the programmer. To reprogram it, you would just 
remove the eprom from the m100 module, so you wouldn't need any special 
pin-remapping adapter, and you wouldn't need a Molex socket either.


  That module needs to use a surface mount plcc socket (through-hole sockets 
are too tall), so it's impossible to solder with a pencil.
  I have assembled a couple of those boards using nothing but flux, solder 
paste syringe, and a $22 heat gun off the shelf at a local store:
  
http://www.microcenter.com/product/391369/Multi-Function_Mini_Heat_Gun_with_2_Speed-Temperature_Settings

  http://www.microcenter.com/product/444659/SRA_Low_Temp_Solder_Paste_-_053_oz

  http://www.microcenter.com/product/444655/SRA_No-Clean_312_Flux_Pens
  Oh and these...
  https://www.amazon.com/Reading-Glasses-Lighted-See-Clearly/dp/B007U7IF8K/

  That heat gun is NOT a really intended for soldering. I just used it to prove 
if one could or not. The answer is if you are careful, yes you can. The point 
is, you don't HAVE to spend a lot on tools if you don't already have a full 
proper soldering station. Good tools are better, but it's not a bar to entry.


  I am still waiting for some plcc 28C256 to come in the mail, so it's not 
tested yet.

  Even if it checks out electrically, the steps to build are kind of janky.
  You have to sand down two sides of the plcc socket to make it fit inside the 
Molex socket, and you have to further sand a chamfer on two edges of the plcc 
socket so that they don't push on the pins in the Molex socket, which would 
push the Molex pins away from making contact with the "castelated" terminals on 
the pcb. Plus the hot air soldering is trickier to get right than soldering the 
soic chip with a pencil. So I don't know if this is preferable to the soic chip 
module or not.

  I have also recieved my order of 9 carriers with 27C256 in them too,

  http://www.ebay.com/itm/262794713841
  and have taken an original Model 600 MultiPlan rom and copied it to a new 
27C256 and installed it and ran it. It worked!.

  So, if we can ever find the basic rom, or any other rom, there is no problem 
copying it and writing it to a new eprom.

  I went ahead and dumped the other 4 system roms too. They are all the same 
HN613256P chip, and all socketed, so it's nothing to read them, edit them, and 
write the hacked copy to a new 27C256. Don't even need the special Molex 
carrier for those. (not that I'd have a clue where to begin picking them apart 
to actually hack them.

The most recent version 1.41, supports serial and Bluetooth connections. I have 
not tested it with BlueM. I tested with an off the shelf Bluetooth to rs232 
device. The problem is with TS-DOS. There is too much delay with a Bluetooth 
connection and so TS-DOS times out.

I ended up tweaking a RAM version of TS-DOS and adding delays to it. On my 200 
it worked perfectly but definitely slower than a wired connection. I carried 
those changes over to the ROM versions of TS-DOS that are in the members file 
area under my name. They have not been tested.

Steve did some limited testing with BlueM but I don't think he had satisfactory 
results. Perhaps he will comment.

To try it, you have to first create a Bluetooth link between your phone and the 
Bluetooth device. Then start mComm. The little serial cable icon is a button. 
If you press it, mComm will switch to Bluetooth mode and the icon becomes a 
Bluetooth symbol. Then when you press the "Start TPDD service" button, it will 
ask you which Bluetooth connection you want to use.

One thing I did notice is that TS-DOS needs to be running before you start the 
Bluetooth connection or it errors out for some reason. There is a lot of 
testing and debugging to be done on the Bluetooth side.

Not necessarily, they may just be late model M100 RAM upgrade modules; they 
certainly look cheaper to build than the original 4 chip version.

My memory ain't what it used to be, but ISTR seeing modules like that before 
somewhere; I'll have to dig around a bit.

The single chip RAM modules in mine are different though; they use a full-size 
6264 RAM chip with *two* support chips on the bottom.

Re: [M100] mComm 1.5

[Mike Stein]

When I used the M100 on the 'net I set the bridge to send  1 byte packets to 
the M100, although a larger number like 8 would probably have worked as well 
since there are 24 bytes available.

  The only time I've seen it go over 64 was when stepping through the T-Word 
code and watching the buffer byte while sending a track (128 bytes + header) 
from sardine.But I may have been watching the wrong byte in memory.


  As far as the 64 byte limit, I had a heck of a time getting that to work 
properly with the Android device. With Windows, the XON/XOFF works pretty well. 
I ended up sending 8 byte chunks and then checking for a flow control byte. A 
pain, but I think I have the timing right.

  Steve played with expanding the buffer a long time ago while we were playing

  John, Thanks for info. Is that a TELCOM limit? The reason I ask is 
because when running virtual T with TS-DOS, I notice that the buffer can go to

In my experience I've found that all 8-bit bytes go to 2^8 - 1 = 255


Just teasing :-) It could but it should never in practice have a value > 64.
Have you observed a higher value than 64?


It's not a limitation of TELCOM per se, it's a limitation of the receive 
interrupt handler logic and the size of the circular queue-on-array reserved 
for receiving bytes. The same receive handler is used for TELCOM and BASIC 
access to the serial port.


See http://www.club100.org/ftp/m100-hiddenpowers-3.pdf
Page 186


It shows a receive buffer of 64 bytes. If it went beyond the bounds, 
unmasked, I would expect it to corrupt other data structures.


The high-water mark for the buffer is 40 (the point at which the receive 
handler sends XOFF), which probably makes more sense in the context of a 64 
byte buffer than a 255 byte buffer :-)

Re: [M100] Doing what the C= can do?

[Mike Stein]

As a matter of fact I see Jim Brain (who's behind Retro Innovations) from time 
to time; he's quite well known in the Commodore (especially 64) world for his 
many very reasonably priced adapters and various add-ons. There are also a 
number of other folks building and selling various gizmos for Commodore 
computers, many of them overseas in Europe and Australia.

Schema, the fellow who designed and built that modem, happens to be a neighbour 
of mine and a fellow board member of the Toronto PET Users Group (TPUG); again, 
there are (and were) other similar devices around but none quite as fancy as 
his.

I think you've explained very well why there are so many more goodies available 
for Commodore computers (again, mainly for the C64). 

Obviously there are many, many more C64s, C128s, Amigas etc. and their users 
out there than there are Model T's, and also proportionately more tinkerers 
designing and building various accessories; I think you can count Model T 
developers on one hand with our own Ken and Steve at the top of the short list, 
whereas there are way more folks building stuff for the C64.

I don't think cost is a big factor with these items except for the occasional 
item that can sell enough for real economies of scale; most items are pretty 
reasonably priced, both in the Commodore world as well as for our beloved Model 
T's.

And yes, although I wouldn't call the Model T inferior, its small memory and 
lack of colour and sound seriously restrict game playing and therefore leaves 
out a lot of folks. It's really a different kind of computer; it does what it 
does extremely well but by its nature has a much smaller user/fan base. Another 
factor is the Model T's portability; you can only have so many gizmos hanging 
out the back before it becomes a desk top, and what's the point of that.

I haven't followed it too closely but I thought it IS possible to work with 
documents larger than 32K, no?

But I think the bottom line is that there just aren't that many people 
interested in, knowledgeable enough or with enough time (and sometimes money) 
to invest in building hardware add-ons or writing new software to expand the 
M100's capabilities; I think we're lucky to have as many such folks (and their 
contributions) as we do.

Besides, we doan' need no steenkin' modem to get on the 'net; we can use our 
Android phones!

  The Store for that site has all kinds of hardware projects.
  Is it that much more expensive to develop such projects for the M100 as the 
latter site has for the C64? Is it that the user base is so much smaller? Or is 
there something inherently inferior in the M100's design that doesn't allow for 
it? I've been busy with other things, but iirc, the M100 does have an expansion 
port, yes? Which can directly access the M100's memory?

  I'm rehashing topics I've discussed before, but among them is some kind of 
MMU for the M100 so it could have relocatable code (again, iirc, the 8085 
doesn't even have relative addressing?) .

  The things that frustrate my ambitions with the M100 most are the memory 
restrictions and the slow refresh on the display. I want to be able to work 
with documents larger than 32k; I could live with the slow refresh if I could 
do that.

  Anyway, I was just hoping, with those links, to inspire some hardware types 
into thinking "why not?"

Regarding the WiFi modem, there's no need to build anything; one of the 
advantages of the M100 over the C64 is that the M100 has a standard RS-232 port 
capable of speeds >38Kbps and RS232 WiFi modems are available off the shelf; as 
mentioned, you can also use an Android phone or a Pi as a 'modem'; 

One way or another the Model Ts have always had Internet connectivity, but the 
real issue has always been what to do with it; browsing the web or even email 
gets stale pretty quickly with the small screens. Of course you can run it in 
80x24 mode on an external display but now you've got that extra hardware and 
you're still pretty limited in what you can actually do.

  Yes, you can build a similar device for the m100.
  For relocatable code, you can use a fixed-in-memory small routine to 
trampoline relatively to the caller's program counter.
  For a faster display, disable screen scrolling and there is a program for 
this in the library.  Note that the screen refresh is not all bad if you are 
starting from a blank screen, as it will go faster than you can read.   :-D

  I came across this video on Youtube of a wifi modem for the Commodore 64, 
that was able to load software directly from the internet.
  C64 WiFi Modem

  Watching that and related videos, I came across this site...
  Retro Innovations

  The Store for that site has all kinds of hardware projects.
  Is it that much more expensive to develop such projects for the M100 as the 
latter site has for the C64? Is it that the user base is so much smaller? Or is 
there something inherently inferior in the M100's design that doesn't allow for 
it? I've been busy with other things, but iirc, the M100 does have an expansion
