You might also need to set MAXFILES to 2 at the beginning of your code.
5 MAXFILES = 2

You will have to open COM for input as well:

10 OPEN "COM:78N1DNI" FOR OUTPUT AS 1
15 OPEN "COM:78N1DNI" FOR INPUT AS 2
20 ON COM GOSUB 100
30 COM ON
40 REM Send seek to frame 1000
50 PRINT #1, "FR1000SE"
60 REM when the player gets there, it responds "R" via serial
70 GOTO 70
100 REM Got serial response
110 A$=INPUT #2
120 PRINT "Got ", A$
130 RETURN

Or, something along those lines.

Subject: [M100] Serial IO from BASIC

Hi all.

So I'm working on a project; a BASIC program that talks at 4800 baud to a
LaserDisc player.  The commands are sent as ascii text, with a carriage
return at the end, and responses are similarly a text string terminating in
a CR.

On my Tandy 200, I'm able to configure the port in TERM via:
   STAT 78N1DNI

And then i can type out commands and the player works and responds with the
correct responses... so I know the serial line is working in both
directions as designed.

In BASIC, i know i need to open the connection for INPUT and OUTPUT so that
I can write stuff and read back the responses.  The following code works to
send out the commands, but it gets errors no matter what I try for reading
in the response

10 OPEN "COM:78N1DNI" FOR OUTPUT AS 1
20 ON COM GOSUB 100
30 COM ON
40 REM Send seek to frame 1000
50 PRINT #1, "FR1000SE"
60 REM when the player gets there, it responds "R" via serial
70 GOTO 70
100 REM Got serial response
110 A$=INPUT #1
120 PRINT "Got ", A$
130 RETURN

I looked around in a few online T books, but couldn't really find anything
that could help me out on this one, and I'm feeling pretty stupid that me,
a web applications and embedded systems engineer can't figure out a BASIC
program It's been YEARS since I messed around with BASIC, and even then
I never really did much with opening files...

sidenote, "ON COM GOSUB " ?!?! That's an awesome feature!  I love that
we can have interrupt-driven serial in BASIC!

Side-sidenote; I also don't really have a good solution yet for saving and
restoring the files but i'll probably just do serial port dumps or
somesuch. ;D I know i can buy NADS or REX or something, for file offloading
but this is a short-term project for Maker Faire next month, and I don't
have the cash to drop on fancy stuff right now.  I'll probably just throw
together a serial-terminal based SD card shell using a spare arduino or
something...   Although I'd gladly trade my Booster Pak which i never
really got working for one of those... ;D

Hey Gang,

I had reported a couple of weeks ago that I had maybe a dozen NADSBoxes 
that I would be able to sell fairly soon.  Just wanted to updated 
everyone that the effort has kinda been put on old for a bit because I 
was in the hospital the past week and a half.

I went in last Monday because I felt I needed more stents, which I did.  
They ended up putting in 2 more stents ... I think I'm up to 20 now.  
Normally this would be a 2-3 day visit to the hospital and then back to 
work the following week.  But this time because of the amount of 
blockage in the main artery, they needed to put me on a breathing 
machine and sedate me fully (in an expeditious manner since they only 
discovered this during the proceedure).

While placing the breathing tube, they lacerated the right side of my 
tongue REALLY BADLY, then I spent the next 7 days in the ICU.  I just 
got home on Wednesday evening and am still recovering with a swollen 
tongue and neck (secondary brusing from all the bleeding).

I still plan to work on these over the next few weeks, but it will have 
to be at a slower rate than I was originally thinking.

Hello to the group. I just got hold of a very nice T102 with T-Dos in rom and 
am trying to copy some files to it

from my Thinkpad 380xd laptop but can’t seem to get it to work. I made up a 9

I have set the Thinpad to 19200,8N1 xon/xoff, I start Desklink and it says I am

on the T102 and get the ram file menu, I then press F4(Disk) and it goes to the

directory or files and the screen locks up and I have to press shift break to 
get back to the Ram file menu. I have

tried the Tiny program which starts up fine but when I press a key on the PC 
the program closes. I tried a connection

using Termite and Telcom and was able to get a connection. I’m now at a loss as 
to what to try next.

Re: [M100] VirtualT and REX 4.9

Kurt,

 

After MANY tries at this, I finally figured out that the filename errors that 
RF249.CO was throwing were due to the fact that I had a dash (-)  in my VT root 
directory name.   After I figured that out, it was clear sailing!

 

It is so nice to have REX 4.9 running in VT 1.7.

 

Thank you so much for your patient help!

Select the radio button that says "Connect to simulated NADSBox".

 

Then click the 'Configure' button underneath that radio button. That will allow 
you to select the root directory. By default it is the same directory that 
Virtual-T is running in.

 

That root directory is where you want to drop the three files.

 

Hope that helps.

Re: [M100] T200 Restoration and Mods/Playing

[Bob Pigford]

EME (owner and inventor Tracey Allen) made and sold an OptROM for data 
gathering and dumping to higher computers.  He named it the OWL  for onsite 
weather logger.  I have one along with the EME A/D board made as an inclined 
plastic stand for the M100.  The board includes a gell battery so it will 
survive power dips.  Quite a terrific piece at the time.  But the A/D inputs 
are only 8-bit so the fidelity is somewhat limited.

 

EME systems now makes later generations of the same concept for data gathering:

https://www.emesystems.com/loggers.html

 

I think that Tracey’s OWL firmware/software for the Model100 is not in the 
public domain and probably is still copyrighted.

 

Might your OptROM be an EME Systems OWL?

After the fun with my T102 I decided to continue the fun with a busted T200 off

populated and an EME ROM, which doesn't seem to do anything, calling 63012 
locks is up, and 63013 returns OK with nothing else obvious.  No NiCad or Y2K 
mods yet cause I ran out of parts, waiting on Digikey.

 

Well I got bored waiting on Digikey and thought, how fast can this thing go, so 
I swapped the 4.9151 crystal with a 10Mhz (all I had in-stock), and it boots 
and runs!  So I quickly threw this program together, prime number example I 
found online modded to time the loop:

 

1 POWER CONT

10 CLS

20 PRINT "LIMIT";

30 INPUT L

31 HH$ = LEFT$(TIME$,2)

32 MM$ = MID$(TIME$,4,2)

33 SS$ = RIGHT$(TIME$,2)

37 SEC = VAL(SS$) + (VAL(MM$) * 60) + (VAL(HH$) * 3600)

40 FOR N = 3 TO L

50FOR D = 2 TO (N-1)

60  IF N/D=INT(N/D) THEN GOTO 100

70NEXT D

80PRINT N;

90GOTO 110

100   PRINT ".";

110 NEXT N

111 HH$ = LEFT$(TIME$,2)

112 MM$ = MID$(TIME$,4,2)

113 SS$ = RIGHT$(TIME$,2)

114 SECE = (VAL(SS$) + (VAL(MM$) * 60) + (VAL(HH$) * 3600) - SEC)

117 PRINT "Duration = "; SECE ; " Seconds"

120 END

 

Duration factory = 43sec, duration overclocked = 21sec!  (with an input of 100)

 

It isn't completely stable, sometimes I have to power it on 2-3 times, but once 
on it doesn't seem to have any trouble, aside from the clock resetting on 
occasion.  I've not yet studied the schematic to determine if it's because 
10Mhz isn't a multiple of the factory 4.9152, or because it's simply too fast 
to read properly, but I'll figure it out.I ran the above to 1000 a few 
times without issue or any lock ups.  File transfer even works if I set my PC 
to 2400bps and the T200 to 1200.

 

Overclocked comes at a 20mA over stock hit.

 

Fun fun, happy Friday.

BR,

Andy

[M100] VirtualT and REX 4.9

[Bob Pigford]

Hello all.  I have struggled to configure VT for REX 4.9.  I understand
REXMGR and the OptROM.BX files, but I can't seem to figure out which files
to have and in which folders they should reside for the REX 4.9 version
(via REXMGR) to appear.   I would like to try again; I use the T200
emulation most of the time.

 

My searches for installation instructions have not been successful, but of
course, I am not the sharpest knife in the drawer.

 

Where might I find these instructions?

 

Thank you!

 

Bob

 

Re: [M100] odd REX error - anybody run into this?

You might try unseating REX, checking that the metal fingers in the socket
are all ok and working, then re-seat REX.  Just trying to think of
something.

My son's REX (in his M100) is in a strange state.  I don't know what exactly
he did just before initially getting this message, but now he gets this
every time he runs REXMGR.  The REXMGR screen appears with the top line
saying "REX 4.9  M  Group:RAM" and the rest of the screen blank except
for the following on the bottom line: "no blank sector pair found"

Cold reset and CALL 63012 just leads back to the same screen.  The "no blank
sector pair found" message is flickering every second or so, as though it is
being re-drawn.

Any ideas?  Is there a possibility of recovering from this with the contents
of flash intact, or are we going to have to go straight to reloading REXMGR
into the module so it re-formats the flash?

and a logic chip (there're a few different approaches here) to combine
the separate chip selects to a couple of addresses and a single select
signal. My own version of the circuit uses the fewest ports possible
(at least if nobody comes up with a different approach I couldn't
think of).
The RAM chip must be a CMOS static ram, 8kx8 and with low power
standby (not all have this feature). The original 8k modules were
specified for 4 uA max standby current, that allows the standby
battery to keep the RAM content for over a month. Usually the suitable
chips have L or LL in the part number, but you better check the
datasheet for the fine details. Most of the suitable RAM chips have a
measured standby current of 0.1 uA (often less) at 3.3V if the chip
select are driven with the correct voltages. At these current levels,
cleaning the soldering flux is a must. I've measured up to 15 uA of
standby current on badly cleaned modules. YMMV.
Glue logic *must* be 74HC family, it has a suitable current draw at
3.3V standby and suitable speed. In one case I've used 74AHC and it
worked well too.

All of the discussion about getting DVI to work and a modern DVI solution made

while using RaspberryPi was maybe the cheapest solution, somehow it never sat 
quite right with me to use a 1GHz processor with 1G RAM as a display terminal 
for a 2.4MHz / 32K processor.

Like it has already been stated, if you are throwing a Linux box into the mix, 
then why not just run VirtualT on the thing and be done.  
Especially if you are bound to a dispay anyway.  Somehow using a lower-end 
microcontroller with a VGA output from a CPLD / FPGA always seemed like a more 
"retro" solution.

Am I crazy for thinking this way?  Or do the majority of people not really care 
about "retro" value and only care that it is dirt cheap (or as close as 
possible)?

Just curious.

I've never seen a CP/M clamshell laptop before, and this is a Bondwell, which 
at the time was a "mainstream" brand.

The keyboard layout made me think of the NEC 8201 version of the M100. I think 
it's got CP/M in ROM, so maybe if you do a ROM dump it might give some info 
that can be use in the M100 port...?

At the moment it's cheap, and while I have no use for it, I couldn't let it

Re: [M100] Tandy 102 Text question

[Bob Pigford]

Ron,
On one of my Arduino projects I finally gave up on SoftwareSerial on an Uno and 
went to a Mega so I could have several real serial ports.  As I recall, there 
are a total of 4 available (don't remember the pin nos.).  Something like ...
 Serial.
 Serial1.
 Serial2.
 Serial3.

Example for the first 2 hardware ports on a Mega:
void setup() {
  // initialize both serial ports:
  Serial.begin(9600);
  Serial1.begin(9600);
}
Thereafter I had no serial issues.  I realize that you have probably already 
tried this, but I offer this small thing from my experience.

I'm making the assumption based on the fact that the Arduino is faster.  But 
it's just an assumption.  But I did do a SAVE "COM:98N1E"

For debugging right now, all characters that enter the Arduino are echoed out 
the USB/Serial.  So I can see everything that arrives on the serial connection.

Re: [M100] BASIC renumber utility *for modern computers*

Well,  it is not a compiler, but VBASIC by Dr. Verts does remove the need for 
line numbers.  It runs in the Model Ts and it can also eliminate line numbers 
in GWBASIC.  Some time ago I posted it in our Member Pages:

 

http://www.club100.org/memfiles/index.php?PHPSESSID=g1mcuaji7l2sgtab816g0t8pj7 

 =0==Robert%20Pigford

 

Obviously, ModelT statements like PRINT@ will all need to be converted to 
LOCATE x,y for GWBASIC.

 

But, yes, a true “a structured BASIC to Microsoft BASIC compiler” would be very 
nice.

Re: [M100] Loading multiple .DO files with TS-DOS

[Bob Pigford]

Gary,

 

Sometime back I was having the same problem.  

 

Using a HEX editor on the .DO files on my PCs hard drive, I found that some .DO 
files had  an EOF (1Ah) as the last character.   Model Ts do not like this as 
the operating system appends its own 1A to the end when the file is in-loaded 
to RAM.   And as long as that .DO file sits in RAM it needs that 1Ah.  But when 
a file is out-loaded from RAM, the op sys removes that 1Ah.  

 

I traced this problem to an early version of VirtualT.  When I created a .DO 
file in VT then saved it to my PC’s hard drive, VT was not stripping off the 
1Ah when saving the file to the host’s hard drive.  So, when in-loading that 
.DO file I ended up with two 1Ah’s causing a weird phenomenon where the RAM 
file directory was corrupted, shifting the directory values.  Of course Ken 
quickly found that bug and fixed it.

 

I also found that some PC word processors append either a 1Ah or a null to the 
end of their text files, but I could not pin down which applications were doing 
that.  I am still finding some if my old .DO files that have the nasty 1Ah at 
the end.  Ugh!

 

Having a CR/LF at the end of the .DO file was not a problem, but I did not run 
into the CR only (or lack of the LF) at the end of a .DO file, but perhaps my 
study did not create and test that condition.

 

Hope this helps a little.

 

Bob

That may be true, John. I have not had to deal with the CR vs CR/LF issue for 
quite some time. As I recall it messes up the file but I'm not sure about the 
file system.

 

Could this be an EOF problem? Looking at the memory editor in Virtual-T, every 
DO file has an EOF (0x1A or CTRL-Z) at the end of the file. BA and CO files 
don't have that.

One thought. The Model-T needs a CR/LF and sometimes when a file is saved on a 
different system this can get converted to CR only.

That shouldn't affect the file system.  

 

I thought only nul's and EOF were disallowed in DOs?

Re: [M100] Tandy 102 with BoosterPak on eBay

[Bob Pigford]

I see that the Booster Pac has a Sardine OptROM in it.  If the dictionary disk 
comes with it, the long lost M100/102 dictionary data that Kurt McCullum has 
been seeking might be recovered. 

I will email the seller and see if he has that disk.  I doubt it, but it is 
worth a try.  

More later.

Just want to remind folks that we have a long standing no politics rule on the 
list.

That includes the entire content of emails, including signatures.

 

This is to keep our nice friendly atmosphere. Let's protect that. We'll leave 
the political excitement to Facebook and Twitter.

Other rules: no swearing. No personal attacks. No spamming with ebay links. 
Keep it on topic as much as possible. Be nice and respectful to others. Try to 
avoid flame wars. Conflict happens! But we have to resist it and try to resolve 
quickly or take it off list.

BTW, as of this moment, we have 357 subscribers to the Bitchin100 list! I think 
our unique atmosphere contributes to keep that number high.

Hi Joshua, and welcome!

 

I'm the guy who suggested you join up here and I hope you'll find the answers 
to your questions; I see Bob has already helped with advice about separating 
the case halves.

 

My personal preference for prying apart cases held together with tabs that are 
not too tight is an old credit card; it doesn't scratch the plastic as a metal 
tool might.

 

You can attach pictures to messages here but the total message size must stay

Hi all, 

 

I'm new to the mailing list. I was referred here from the vcfed forum.

 

I have a Tandy 200 that needs some help. The power key is damaged and 
disconnected from the keyboard. I have a pdf of the service manual, and I'm 
trying to disassemble the device so I can check the internals and reattach the 
power button if it is serviceable.

 

So far, I've removed the monitor and the four screws holding the bottom case, 
but I'm encountering a lot of resistance when I try to remove the top half of 
the case. Before I damage something, could anyone tell me if I've missed a step?

 

Some forewarning: I'm a newcomer to vintage computing, and I only have basic 
electrical experience. I've got to start sometime though, and I'm willing to 
learn.

 

Any help you can provide me will be appreciated!

Re: [M100] Tandy 200 repair, guidance requested

[Bob Pigford]

Joshua,

 

Welcome to the ModelT list.  There are many more qualified and experienced 
members than I, but I will try to help.   If you have already removed the LCD 
screen assembly, you have already dealt with the plastic cover that is snapped 
on to cover the LCD ribbon cable, and you have released that ribbon cable from 
the LCD screen assembly’s compression connector.  With the ribbon cable 
disconnected, there are only screws (4 I think) to remove to allow the LCD 
assembly to separate completely from the base/top assembly. 

 

As you noted,  the four screws on the bottom of the T200 need to be removed.  
There are two “halves” to the machine: a beige top and a black base.  During 
assembly, the top is snapped down onto the base over molded-in plastic 
“catches”.

 

The way I have gotten the top off is to use a 1” wide blade putty knife.  I 
slip it between the top and bottom and move it so as to “lever” the top away 
from the base (out, not up).  Do not use excessive force when prying.  The top 
has to flex outward only a little bit to release the catches allowing it to be 
lifted off.

 

Sometimes I have had to do this maneuver on the other sides as well.  For 
reasons that I cannot remember, I usually start prying near the middle of one 
of the sides, not the front or back; but this may not be important.

 

I also remember having used a flat screw driver blade as my pry bar.  Usually 
the thickness of the blade inserted up under the top about 1/8” is sufficient 
to move the top away from the base and allow it to release.

 

I hope this helps!  Good luck!

Bob

Subject: [M100] Game idea

Hey gang,

After integrating AsciiPixels into TextSweeper, it got me thinking about 
another game idea using AsciiPixels.  I spent a few hours coding up a BASIC 
program on the T200 (using VirtualT) to get an idea if it would work / how it 
would look.  It could be coded for M100 also by scrolling and showing only half 
of the screen (upper or lower) at a time.

Written in BASIC, it is a bit slow, but was okay for "proof of concept".  Plus 
BASIC doesn't require 2x the RAM like .CO files to (one copy for the .CO and 
another for the HIMEM location where it gets loaded).  Maybe a full .CO 
implementation is the way to go? Currently the implementation has only the 
ability to build and display the board and no logic for choosing or removing 
pieces. Also, the board build logic is purely random with no attempt to add 
game theory for determining if there is a winning solution.  This would all 
need to be added.  The BASIC program is currenly 42 lines long (with multiple 
statements per line) and is about 2K in size, plus another 1300 bytes for 
AsciiPixels resources in a separate .DO file.

Anyway, I though I would share a screen capture of what I have and see if there 
is any feedback on interest level.  And yes, I intentionally didn't say what 
type of game so that you can discover it by watching the
video:

It says that to do a Cold Start, you hold down the Ctrl Key along with the 
Pause Key (both at the same time), then press either the Power On/Off button or 
the Reset Button and release it (then release the Ctrl and Pause keys).  Even 
though your keyboard seems to be inoperative, it is worth a try.

 

A Cold Start will completely wipe the memory and restart/reload the operating 
system from the onboard ROM.  So a Cold Start wipes out any user files you 
might have made.  Since your keyboard is not working yet, you probably have no 
user files loaded anyway,.

 

It is best to use an AC adapter (wall wart) to recharge the internal NiCD 
battery, I THINK.  It may recharge from the AA batteries as well, but I am not 
sure about that.

There is a note on Club100 about how what wall wart and connector are needed.

Ref:   <http://www.club100.org/library/sup/05.txt>

These wall warts are different from the ordinary as they are Center Negative.  
Some people have adapted other (nominal 6vDC) AC adapters by soldering the 
correct barrel plug on while respecting the need for Center Negative.

After you do a cold start, you have to cycle the power off-then-on again.  It

If you can find an all in one that meets these properties then it should work. 
Be aware though that the shell on same cables is too large and it bumps into

That's a real shame, Ken.  The NADSBox is amazing, and I use it all the
time.

I recently got a REX card from Stephen Adolph and that, in combination with
the NADSbox, make my T102 a truly useful everyday tool.

I think a REX card in combination with the DeskLink TPDD emulator running on
your Windows or Linux computer would be a good solution in lieu of a
NADSBox.

Re: [M100] Problem with OptRom REX on M102

[Bob Pigford]

I agree with John about being careful to unplug all cables, including NADSBox.  
Even an attached printer cable can provide enough power to fool a cold reboot 
and the memory power switch.  That one had me confused many times, but I 
learned (albeit slowly).

Just to clarify when you are trying to drain the power you need the memory 
power switch off, no batteries in compartment and no cables whatsoever 
connected. 

 

It really doesn't take much to keep the memory partially intact.

 Hello All,

 I saw this posted on a Facebook group and it got me thinking. I wonder if
 this could be repurposed (with some ancillary hardware and ROM tweaks) to
 give the Model 100/200/102 an external VGA display for very little money:

 http://www.hobbytronics.co.uk/serial-vga

 It accepts serial data and drives a text based VGA display at 800x600
 resolution. Additionally, it understands escape sequences to manage simple
 text windows, etc. It's pretty cool, and it got my wheels turning.


Says the source code is available so you could modify it to handle the
full character set and raw escapes.

Subject: [M100] Replacing the internal in a Model 200

Whilst I'm on the list

I hope no-one is offended by the idea of using the Model 200 shell and keyboard 
as a housing for more modern components. I thought about this for the Model 
100/102 but the aspect ratio of the screen does not lend itself to finding a 
modern equivalent.

I have found a 7 TFT screen that will fit within the existing bezel of the 
Model 200 and would be looking to install a raspberry pi with an arduino 
providing the conversion between keyboard and USB.

Has anyone tried this before? I haven't come across anything on the net (so 
far). Would be interested in people's thoughts.

BTW - this came up on the Retrocomputing Rountable Podcast in a recent episode 
(http://rcrpodcast.com/)

http://hackaday.com/2015/06/01/hackaday-retro-edition-the-radio-shack-roomba/

Thought if you hadn't seen it might be of interest.

Regards, Mark.

Re: [M100] TDock

[Bob Pigford]

I agree with Van and others:  TDOCK needs to be a Dock (not portable) and
may be powered with a wall wart.  For me, an 80 X 25 display would be the
ultimate goal, not just duplicating the ModelT screen on a larger display.
For instance, I think one might already be able to run VirtualT on a
Raspberry Pi and have a virtual ModelT on a larger screen, but what is the
point in that.  

 

I want to have the great ModelT keyboard, serial  parallel ports, etc, on
my desk while looking at a full screen of characters.  The hardest part of
that might be the changes to the ROM.  I will point out that Steve's REX can
be operated in ROM replacement mode such that a custom modified soft ROM
(adjusted for 80 X 25 display) can be used without actually creating or
requiring a new physical ROM.

 

SD card storage in TDOCK would also be terrific freeing the serial port for
BlueM.

 

I think that HDMI may be the best video solution for TDOCK, and there are
many small HDMI screen choices available.  For example, see
http://www.adafruit.com/category/63  

If you only have a VGA screen, then an HDMI to VGA adapter could be used.  I
am doing this now with a RPi and a VGA screen.

 

I think that Wifi and internet connectivity delivered directly from TDOCK
might be way down the road, but Ken's initial design could allow design
space for that later enhancement.

 

As to Ken's question about I/O capability (like A/D and digital pins), that
would be nice but not necessary.  If you want to touch the real world of
sensors, motors, and the like, a serial connection to an Arduino will
suffice (cheap hardware and easier programming on the ModelT end).  Of
course, if a Raspberry Pi were to be used as the engine under the TDOCK
hood, I/O pins and HDMI are already there, as well as USB ports for add-ons
like Wifi.

I'd also like to add that your original idea of making this interface with
the parallel port is a definite must. For one thing, it eliminates the need
for multiple iterations of TDock--one size fits all. Also, to accommodate
the 5 people that still use a printer and would even buy a TDock in the
first place, there should be the parallel port pass-thru option, thus making
everyone happy :)  This would keep the system bus free for some memory
upgrades or something, as originally suggested by Stephen Adolph.

Hey Ken,

I'm so glad you posted this because I've been wondering how the project is
going.

Personally I'd like to see a modern video interface. Maybe not the old VGA
standard specifically, but something fresh like HDMI that would work with a
myriad of high res TVs and monitors nowadays. WiFi and RJ-45 network
interfaces, as well as SD storage are also high on my list. Additional sound
hardware would be nice but it's not a priority to me. 

Just my $0.02 :)

Bob asked about the status of TDock the other day and it made me think about
it with the very ew background cycles of spare though time that I have.  But
it made me wonder, what should be the focus of such a device?  Long battery
life with WiFi and SD card access capability (along with VGA)?  An added
HDMI output and USB Host port with shorter battery life?  Added support for
generic digital and /or analog I/O (DACs, ADCs, etc.)?
