hi all!

forgive me for not replying to the relevant thread as i just joined the mailing 
list a few days ago.

i recently spent a ton of time trying to track down an archived version of 
Radio Shack's Assembler/Debugger (23-3823).

i got lucky that it was being discussed here on the mailing list right when i 
joined, and i was able to get a copy from the link joshua provided.

i was wondering if it would be okay with joshua if i (or someone else) uploaded 
the zbug manual and binary to archive.org so it is easier for others to find. 
because it's known as zbug to many people, that doesn't make it easy to track 
it down with only the original title.

an archive named "Radio Shack Assembler/Debugger - 23-3823 (ZBUG)" would help a 
lot of people find what they are looking for.

i'm sure it's fine, but i figured i'd ask first since it's on joshua's site and 
i don't really want to upload it without permission.

Joshua,

  Thanks for the link, I will check it out. But yes, I also want the
physical package for the full retro experience


 If you're just hoping to use the software I have the Tandy
 editor/assembler debugger in my bucket[1], along with the manual.  I
 believe it has been labeled variously "ZBG" or "EDTASM" (as other Tandy
 assemblers) as well.  The underlying assembler and debugger are the
 Microsoft package, I believe.




Randy,

  I know you have one, as I saw it at Tandy Assembly in 2019 when I was
sharing your display table. I didn't know it before I arrived, but we were
both in competition on that eBay auction. Haven't seen another one since.

I have the physical package with manual, cassette and hard cover/holder.
 Didn't know it was rare.  I don't want to give it up though.  :).   Sounds
 like it has been archived.




Regards,

Peter

It was definitely an issue with my failure to clear memory. By way of
confirmation, I did the following:

I cold started the M100 and used DL to get TEENY on the M100. I then
used TEENY to transfer ZBG.BA and ZBG.CO onto the M100. I also
transferred the test prog S.DO from the Assembler/Debugger Manual:

 ?? ?ORG??? 0CC00H
HOME:??? CALL??? 422DH
SCREEN:??? MVI??? A,0FFH
 ?? ?CALL??? 4B44H
ROW:??? LDA??? 0F639H
 ?? ?CPI??? 8H
 ?? ?JNZ??? SCREEN
COL:??? LDA??? 0F63AH
 ?? ?CPI??? 28H
 ?? ?JNZ??? SCREEN
WAIT:??? CALL??? 12CBH
EXIT:??? CALL??? 5797H
 ?? ?END??? HOME

Then I entered basic and typed:

RUN"ZBG"

ZBG.BA clears memory sufficiently to run ZBG and runs it...

at the # prompt, I typed:

ASM S.DO S.CO /WE

and watched it do it's magic with no errors. Then I ran the S.CO file
from the Menu and marveled at the speed with which it filled the screen
with pixels :).

Yay! It's just a bunch of calls to ROM functions, still, it's assembly
language and it works!

Wow, is it a memory hog though? - after doing the assembly, I was left
with 500 bytes or so. I realized that a:

CLEAR 0,48000

and running it directly from the menu left me with about 6K, still! Now,
I have something to compare with when I run CZASM and BYTEIT...

Thanks for the assist Stephen.

Re: [M100] Will any old Cassette recorder work?

[you got me]

the resistors are 1/4 watt, so the size is almost always in direct correlation 
to the wattage.
The capacitor size isn't the real issue. You should shoot for a voltage 
handling of 50V to200V.

I am finally coming back around to this, in the absence of other stuff to look 
into... So, I read, reread, and read some more about doing the cassette stuff. 
Apparently, I need a cable :). Thanks for the detailed pdf. I have a scenario 
and some questions based on the reading.

I have a Califone 3132AV Cassette Recorder. It's a classroom model - which 
means it's LOUD (as in massively amplified speaker output) and it has 4, 1/4" 
headphone jacks. Related to the TRS-80 5 pin din to whatever cable, it looks 
like I will need 5 pin male din in the 180 configuration on the m100 side and 
three jacks (3.5mm, 2.5mm, and 1/4") on the Califone side which has a 3.5mm mic 
input, 2.5mm rem input, 1/4" headphone output. But... apparently, it's not wise 
(or useable) to plug in the 3.5mm line out (aux) coming from the m100, cuz 
that's at line level (1 volt stuff) vs the mic which is expecting much smaller 
voltages... So, I need a pad?/attenuator to tamp down those high voltages. If I 
read your email correctly, this is the 2 resistors and a capacitor circuit. How 
do I know what size to make them?

Here is what I think I need (hopefully, fixed font will display properly):

  /- 3.5mm mono jack -> Attenuator Circuit -> 
MIC \
M100 <- 5 pin 180 Male DIN <- -- 2.5mm mono jack -> REM 
  - Califone 3132 AV
  \- 1/4" mono headphone jack -> HP/EXT SPKR
  /

If this is correct. I just need some assist on that Attenuator Circuit...

Thanks,

Will

"plug into the headset jack of your cell phone"

Love to give Texas credit, but I suspect it was because Xfinity “improved “ 
their box.   Oh well.The only reason I added the phone service was it saved 
me $40 over the entire bill to have three services (internet, cable and phone) 
and only cost $30 to add phone giving me a net savings of $10.  I seldom use 
the phone except to answer when my wife calls from upstairs and I left my cell 
phone upstairs.   The old rotary dial phone has a nice loud mechanical ringer.



Sorry about the off-topic post.  There have been some great discussions going 
on lately.   I don’t mean to distract from them.  I like them all.



However, I doubt I will ever use the modem on the M100.   The NEC didn’t even 
bother with the modem.   Back in the day, I use to use a big old acoustical 
coupler modem with the NEC 8201 .   My rotary dial phone would fit one of those 
quite nicely had I retained the modem.



A wild idea for a kluge might be to come up with some electronics that would 
plug into the headset jack of your cell phone and also your M100.Perhaps 
you could establish comm by dialing using the cell then let the M100 talk to 
whatever computer it was you dialed.   I’m thinking the electronics between the 
M100 and the cell phone would simply be signal leveling but more research would 
be needed.



I’ll be quiet now.  ??

I'm also a fan of telecom and I made the built in modem of my m102 (300 bauds

What I can suggest if you would like to experiment a lot with vintage modems ;  
is getting a home PABX (a phone exchange), or a small business PABX (even an 
isdn pabx works) You can find those for anywhere between 20 and 100 
dollars/euros on ebay because nobody needs them anymore, like a 4 lines pabx.



This allows you to have your own PSTN network for your experiments (if you're 
into that kind of thing that is)



I made "calls" between my Model 102 and a USR56K modem with no issue.

You also need a cable. That cable is so vintage that you actually have to 
pickup the phone to make it dial.



Beware that the M100 and M102 do not support DTMF dialing, only pulse, and 
nowadays it's probably impossible to make a call with pulse. You can however 
dial the number yourself (with the above cable) - or, again, use a PABX that 
supports both DTMF and PULSE.

How Do,

The 19, of 19xx, is in ROM. ROM images are available that have the 19 patched 
to 20. This makes the MT good through 2099. The date routines in the MT only 
use the trailing two digits. Burning a single ROM can be a bit much if you do 
not already have the tools. Easiest way would be, check me on this Steve, a 
REX#. The REX has the Y2K patch built in. Greg (Arcade Shopper) should have 
some. If you'd like just a ROM, there's probably some here that could do it for 
you. I have some 27c256 blanks, but my burner is blown.

Subject: [M100] TRS-80 Model 100 schematic transcribed to KiCAD

Hi,

I recently got a TRS-80 Model 100 and for fixing the the main-board I
poured over various scans of the original schematic found on
archive.org; and while it is great that these exist, the original
schematic is still somewhat hard to read, so I decided to transcribe
them to a modern schematic format - KiCAD

I put the schema and symbols file as well as a generated PDF on github
https://github.com/hzeller/trs80-100-schematic

Status: Transcribed the full main-board (not the LCD board). All BOM
entries (number+value) match with the list found in the documentation,
all pin-assignments are accurate. Even deduced some values that are
missing in the schematic (R162, 100Ohm discharging C78 in the reset
circuit, as well as the designator for the 10n capacitor near the
primary in the power supply .. C62). Schematic passes electrical rule
check, so at least there are no obvious mistakes in there.

I tried to keep the original layout as much as possible for easy
recognition, but did slight changes to improve readability.
For instance, I added a gap between the 'analog' and 'digital' part so
that it is possible to print out on two sheets and glue together
without losing content (or simply folding a large print-out without
damaging important stuff). Also using IEC resistor symbols for
readability and changed capacitor units where nanofarad is better
(3300pF -> 3.3nF; 0.047μF -> 47nF); they didn't seem to use 'Nano'
back in the day. Renamed some signals to be more useful, so `Ⓐ*` is
now `RDRW*`. Used color encoding for the different buses on the system
to easier see what is going on at a glance.

If you find any mistakes (I am sure I missed something), please file
an issue in the github's issue tracker.

Cheers,
  Henner.

Re: [M100] Rechargeable batteries

[you got me]

One option might be to install 5 ni-mh cells. 4 in the regular place and a 5th 
inside of the m100. Then have a ni-mh charging circuit (widely available) in 
line with the 6v adapter socket of the m100. So, while the m100 is plugged in, 
it charges the batteries.

Also, I believe there were previous discussions about replacing the memory 
ni-cad with a super capacitor.

Subject: [M100] Rechargeable batteries


I have noticed that with rechargeable batteries the active life for the Model 
100 is shorter. This is because most rechargeable batteries follow a curved 
path for power drain. They only maintain the 1.5 volts for s short time then 
tend to drop lower for the remainder of their power drain. When the power drops 
low enough the Model 100 activates the low power light and then goes down.



There are some exceptions to this discharge path. The EBL rechargeable 
batteries hold the 1.5 voltage across their drain, however then they drop off 
sharply causing a shutdown when they are at the end of the discharge cycle. Not 
really an issue for me as I use the Rex and Jeff’s backpack so I can save often 
on projects. Just some of the tradeoffs I have noticed when using rechargeable 
batteries.



In regards to the backup battery, the advantages do outweigh the disadvantages. 
If you are only running on installed batteries then the backup battery will 
recharge from them continuously, reducing the battery life. However if you use 
a wall outlet or usb power cable then it will extend the life of the batteries 
by charging the backup off of the power cable instead of the installed 
batteries.



I have considered installing NiCad’s, however this requires a little soldering, 
so I am not sure if it is worth it. For now I just use a combination of the EBL 
batteries and a USB power cable I found on Ebay that works really well.



Just my observations on this. Please correct me if I am wrong in any of this.  
Have a great week!

Do you still have the original disk and a tpdd drive?

If so, I can walk you through using pdd.sh to image the disk if you

Even if you don't have a mac or linux machine, I could give you exact

Regardless, the manual alone is great to see. Thank you much.

Does anyone have the software?  If so, I assume that as is typical for M100

  1.  For best results, the Chipmunk drive should have a power supply with at

enough amps.
  2.  These units are virtually indestructible. The weak points being the pins

Feb 25, 2022 4:24:04 PM Stephen Adolph :

So, I burned a ROM and tried it in my T102 (which is socketed).
Interesting results.
It works.
But, visually it is a bit off.  Due to the hardware scrolling, you get wrap 
around of lines the moment you program the drivers to scroll.  Expected.
However, sometimes that means you get a flash of characters where there should 
be none.
This is a bit annoying.

So, I think I need to redo the patch to remove this artifact.
It wasn't the "same" on VT for some reason.

Regardless, I'll work on an improved version.

I've had that Model I disk for a few years and no way to use it.
Now you just provided the COCO version.
And once Greg puts the 100 part up somewhere we'll actually be able to

 From looking at the manuals we do have, it looks like the 100 part is a
client and all the others are servers.

Re: [M100] Cassette woes

[you got me]

I have 'seen' SOUND ON/SOUND OFF have an impact on the computer detecting an 
input signal. It does happen, but may be due to degraded components 
(capacitors?) within the input path as the analog signal gets turned into TTL.

  ah... I disagree.  Sound "on" has no impact.
The SID input of the CPU is used solely to detect zero crossings, and that info 
is used to toggle the PIO that drives the buzzer.

Yes "sound on" can rob some of the signal and/or make it less distinct,

testing to verify that the signal is actually reaching the 100. Once you
have verified that there is nothing obviously wrong with the signal like
it's missing entirely or has scratchy corruption like from dirty
contacts or broken wires or dirty volume pot, or is very muffled and
dull like from excessively dirty read head or missing felt pad in the
cassette itself, then you no longer want sound on for actual reading.

In there I just reminded myself something to check: The felt or foam pad
in the cassette that presses the tape to the head. They are very often
fallen off and lost from the adhesive drying out after 20-30 years.

If you got "file found" but the file was ignore, I think that might just
be a matter of matching up the file name at CSAVE time and at CLOAD time.

When you CLOAD you specify a filename, and it ignores any files on the
tape that don't match.

In general, I've had perfectly expected results with tape. Meaning,
there is a bit of trial & error dialing-in the right volume setting to
get it working the first time, and with every new tape or tape player,
but it's really been no problem, on several different machines and tape
players.

It just doesn't work all by itself like a disk drive does. You just have
to be aware of a few things and you are a little more a part of the
process. Like you the human are one of the components in the system,
detecting and adjusting for several potential sources of variation in
other parts of the system.

Like checking the sound quality with SOUND ON, and testing a few
different volume levels to figure out that "this particular player, with
most tapes, with fresh batteries, and talking to this particular M100,
the best volume setting is 7." and you find "7" by testing methodically
from definitely too-low like 5, all the way to 10, and noting the lowest
and the highest settings that still work, and using a setting from the
middle of that range most of the time. And then deviating from that
sometimes if some particular tape is recorded a little softer or louder
or is worn from being played a lot, or maybe the sweet spot is a little
different on rechargeable batteries (1.2v), vs alkoline batteries
(1.5v), vs using the wall power for the player, or for the 100 too for
that matter. One M100 might be a little more of less sensitive than
another due to slight variations in some of the components and things
like caps aging over time, and things like how one M100 might come from
a an early manufacturing run and another might come from much later
after some revisions and component supplier changes, or one may have
spent the last 35 years in a hot environment or in an environment that
cycles hot & cold a lot, and another might have spent the last 35 years
in a very stable and cool environment.

But even with all those sources of potential variation, it still
actually works pretty well. So I think there is just some relatively
simple thing you just haven't found yet. It still might be anything like
maybe you're still doing something wrong, or some problem with the
player that you don't realize because you don't have 5 other players to
compare against. The first player I got off ebay  didn't work either
(but it didn't work at all, no sound at all), and by now I've gotten 4
or 5 more and at least one of those was bad too. They are all very old
by now and so every one you get might be bad, and it might be only a
little bit bad where it seems to work and make noise, but it's not
accurate enough to actually function for data. Could be slipping old
weak belts, could be degraded caps in the player making weak
amplification or not filtering out hum, could be the speed has drifet
too far out of spec too fas ot too slow or too irregular. It's not like
brand new ones where you can safely assume that if it isn't smashed in
pieces and it works at all, then it's working perfectly within all specs.

In this case I'm guessing you're actually >< this close to working and
it's just something like getting the file name part right, or maybe the
felt pad in the cassette etc.

Re: [M100] Cassette woes

[you got me]

For troubleshooting purposes, load a file from a PC.
If the M100 says "I/O" error it generally means that your signal has been 
detected, but is too low.
If the M100 has no response (ie. you DON'T hear a relay clicking) then 
generally the signal is too high for the computer to see.

Finally, I was able to get the T102 to say "file found" by manipulating the

tape back in the day?  I have tried recording through the mic jack and through 
the aux jack on separate tries. Given that I am having this problem using two 
different machines and two different cables, it seems to me that my problem 
must either be with the cassette player itself or the way I'm trying to do it.  
I suppose it could be that I have problems with both machines and that both 
cables are bad, but that seems unlikely to me. I'm running out of ideas and 
probably losing enthusiasm for this project. I just thought it would be cool to

if the plugs are only colored without labels:
   red goes in mic
   small goes in rem
   white or black goes in ear
   aux not used

If it's the black & grey cable I don't remember which is mic & which is
ear, so just try both ways, but the main point is, it's EAR not AUX or LINE.

deoxit the volume pot and the jacks

volume on "P" if there is a "P" setting, otherwise start on 6 and go up
from there (I don't know about CCR-83, but CCR-82 has a special "P"
setting that makes the volume perfect automatically, & most others do not)

SOUND ON in basic before doing cload to see if the signal is making it
in to the 100

Maybe put a saved search on ebay for CCR-82 and wait for one to come
along that isn't $50 (and order a belt set because the belts are old and
soft in everything by now, if not totally tuned to goo)

pc or other random modern digital audio recorder/player will always be a
50/50 shot in the dark. M100 wants a high signal strength of 2v
peak-to-peak ideally, and a lot of new devices like phones & computers
headphone jacks don't go that high. Sometimes you can get it to work on
100% volume, sometimes not. You have to be knowledgeable and careful
when recording too, to record as loud as possible without clipping. It's
very likely to record either too faint or too loud and distorted from
clipping, if you don't actually set the input levels when recording.
People do it all the time successfully, but it is yet another case of
having to fiddle with volume levels, and in that case both while
recording and then again while playing back.

There's at least one known working mp3's on line you can download to try
loading from pc without the extra variables from recording.

There is a company called Intermec that has the same Everett, WA address

I can't find any pictures of the back or inside, and the user manual
doesn't show anything either.

But this spec sheet does say "Optional 32 KB or 64 KB EPROM cartridge"

... using an external modem on the rs-232 port, wasting the one already
built right into the machine. Philistine!

That neat all-one-piece one is more photogenic than the two loose black
rubber cups and wires though, even if they are smaller, lighter, and
don't unnecessarily consume a useful port.

Or maybe the international model didn't have a modem? I think the
Olivetti is like that, only the NA model has a modem built-in.

not a disk image for tpdd1.

I want to try taking a stab at coming up with some recipe to generate a
disk from scratch. I have a tpdd1 but no original disk.

I figure, if the image existed, I should be able write that image back
to a disk using stuff that's actually already available now, and merely
it just requires documenting the steps.
It might be a bunch of steps, and tedious, but possible is infinitely
better than not-possible, and tedious doesn't matter until after it's
even possible at all.

The M100SIG includes utils that claim to be able to do sector access and
low level hacking/editing on tpdd1, as long as powr-dos is installed,
and also includes powr-dos, and so it may just be a matter of working
out the steps to go from scratch, like to get powr-dos installed using
any number of ways, break up the image into smaller chunks that fit in
ram, etc. Or maybe you can do it by just formatting and writing a couple
files and doctoring the directory table a certain way etc, without
actually copying 100k.

Writing a pc util that just talks to the tpdd directly is another
approach, but that is inventing something new, which may or may not work
or be trivial.

What I'm aiming for is, I think all the pieces already exist and just
need to be strung together.

Maybe this would make it easy to make a new simpler pc util by just

Re: [M100] ba 2 wav software

seems like it would be an easy thing to take a .ba file, read in it's binary 
form and then 'build' a corresponding audio file. The audio file could be built 
by taking PERFECT samples of a '0' and '1' and then spliced together to make a 
whole program on audio. The problem I believe is that a genuine audio file 
produced by an m100 contains more than just the program. I think it also 
contains a '" lead, checksum and descriptor/file name. One of the m100 
books had a description of the audio format.

Thu 8/3/2017, 4:32 AM
The m100 can receive files via the cassette port from almost any audio source. 
The trick is to use a an audio transformer. Something like an 8 ohm to 1.2k 
ohm. The 8 ohm end connects to the output of the audio device. The 1.2k ohm end 
connects to the ear end of the m100 cassette cable.  I have done many 
experiments with this over the years. I called the final project "the Uber 
Cable".  The only things I could not get the cable to work with was
1.
a mini-disc recorder that used a VERY specific type of ATRAC recording 
algorithm (prior models worked just fine) and
2.
super cheap micro cassette recorders. Some of them didn't have adequate signal 
to noise ratios to begin with.

 The cable worked with cassette recorders, olympus i400 mico cassette,  digital 
dictation recorders, Music Cds (with programs on it), tiny mp3 player/recorders 
(like the Iriver T30), and audio ports on a computer, etc. If you make a 
recording of the audio of a m100 program file and want it to be in mp3 format, 
I would suggest a rate of 196k. Lower rates will work, but 196k is a sweet spot.
The audio coming from an m100 is line level. Some recorders only take mic 
level. You will need a a line level to mic level passive attenuation circuit.

As for the original post in this thread A TON of m100 programs could be 
placed on an iriver T30 or equivalent and played back with the names of the 
files on it's tiny display. It could also record the files, but no fancy names 
unless you edit the device. Something small like that would need fresh 
batteries when recording, but it works.

This subject always interests me.  But it is frustrating.

I've been playing around with the files on Sonora.us.  awesome effort to put

1.  The audio files don't work for me in any scenario so far.  I believe that 
at least some of them are distorted.  I have not looked at them all.  When I 
compare the signals generated by an m100 to the audio files using a scope there 
is a really big difference.

2.  As an aside I found that my pc audio output had a DC offset!  That was 
really hard to work with.  I has to make a cable with a series capacitor to get 
the setup to work at all

3.  Once I obtained *good* sample files, the number one determinant of a 
successful readback is drive signal level . Only my PC seems to be able to 
generate enough swing.

4.  Wav vs mp3.  Both are usable.  Once all the issues have been sorted these 
two file types seem to work equally well.  Mp3 a lot smaller!!

5.  T200 is pretty robust and not sensitive to volume that much.  T102 seems to 
be more sensitive while m100 seems on the edge of working at all.  Maybe it is 
specific to my machines.  All the circuits are the same on the schematic so I 
have no explanation.

6.  I use LINE IN for sampling and LINE OUT for playback on the PC.

7.  I amplify the sample files to maximum in the audacity effects menu.

8.  None of my portable devices Samsung s8  old Sony expedia nor my mp3 player 
have enough drive signal to be reliable.


I hate to say it but i believe that the files on the site may need to be 
resampled.  I think the approach of sharing the files over the net is fine but 
the audio files should look like a low pass filtered square wave.  I can send 
traces of M100 actual output of anyone is interested.

Anyhow that is where I got to.  I still don't have a reliable working portable 
solution for cassette audio.

exception of pin 1 which is for address 15. Could a 27C512 be inserted with pin 
1 bent to stick out to the side and then a wire run from pin 1 to the enable 
pin of bank 2? So switching banks also switches OptRoms?

you trim the IC leads.

Another approach to using several and/or larger ROMs is to make a little board

My PC-4 was my constant companion through college and into my first

the pocket computer bug.

What I've put together is this:
+ PC-1 - usually had bad screens over time.
+ PC-2 - frequently people left the AA batteries in them when they
stopped using them.  The batteries leaked.  So always check the
battery compartment before buying one.  Leaky batteries can cause a
great deal of damage.
The printer/cassette interface is where the flaws are.  The printer
gears tended to wear out.  Also the rechargeable battery packs are
shot by now and are leaking.
There are some people who refurbish the printers (new batteries and
new gears), but they will be more expensive.  Surprisingly, you can
still purchase the pens.
+ PC-3 - Not much that I know of.  I only have 1 in my collection and
it has no problems.  The printer even works.
+ PC-4 - No problems with the pocket computer itself that I know of.
The printer batteries are shot by now.  Usually they don't leak, but
the batteries are not meant to be replaced. But with some work, the
printers can be made to work with an AC-adapter.

be careful about the pc-2 and printing. You can always make or refill your own 
pens but the MAJOR problem is a plastic cog within the printing mechanism

My PC-4 was my constant companion through college and into my first
job.  I picked up a PC-2 at the Tandy Corporate auction and got bit by
the pocket computer bug.

What I've put together is this:
+ PC-1 - usually had bad screens over time.
+ PC-2 - frequently people left the AA batteries in them when they
stopped using them.  The batteries leaked.  So always check the
battery compartment before buying one.  Leaky batteries can cause a
great deal of damage.
The printer/cassette interface is where the flaws are.  The printer
gears tended to wear out.  Also the rechargeable battery packs are
shot by now and are leaking.
There are some people who refurbish the printers (new batteries and
new gears), but they will be more expensive.  Surprisingly, you can
still purchase the pens.
+ PC-3 - Not much that I know of.  I only have 1 in my collection and
it has no problems.  The printer even works.
+ PC-4 - No problems with the pocket computer itself that I know of.
The printer batteries are shot by now.  Usually they don't leak, but
the batteries are not meant to be replaced. But with some work, the
printers can be made to work with an AC-adapter.

[M100] What would it take to build a modern DVI?

[you got me]

I'm barely into programming so I can't completely visualize how this would be 
done.

I'm thinking you would still need the m100/m102/m200 cable.


Then interface the cable to a USB i/o device like 
https://ameridroid.com/products/usb-io-board


The device connects to a modern computer that is running a Z80 emulator with 
CRT support like http://www.z80.info/z80emu.htm#EMU_CPU_PCDOS


Now, could the emulator work properly with the data from a copy of the DVI 
ROMs? I know one is bios and the other a character set?


Does someone have a binary file of the boot disk?

I just checked and there was NO article in the Portable 100 Magazines on the 
Club100.org website.

The standard data output of a GPS is NEMA-0183, and is at 4800bps, 8 data, no 
parity, 1 stop. Data is output in bursts every 1 second. There is a newer 
standard NEMA-2000 that has a transmit speed of 250Kbps, but most all GPS units 
should support NEMA-0183.

The standard is well covered here: http://freenmea.net/docs

I am not sure if M100 BASIC alone can keep up with the data bursts and display 
useful information at the same time. A machine language driver may need to 
handle the data burst reception / parsing task.

Depending on the GPS you are using, there may be several sentences in each 
burst. The sentence to start parsing out with is the $--GGA sentence. This has 
the useful basic position information.

Peter

A while back, years ago probably, someone detailed how they used a GPS

Re: [M100] Virtual cassette idea

[you got me]

The m100 can receive files via the cassette port from almost any audio source. 
The trick is to use a an audio transformer. Something like an 8 ohm to 1.2k 
ohm. The 8 ohm end connects to the output of the audio device. The 1.2k ohm end 
connects to the ear end of the m100 cassette cable.  I have done many 
experiments with this over the years. I called the final project "the Uber 
Cable".  The only things I could not get the cable to work with was

1.

a mini-disc recorder that used a VERY specific type of ATRAC recording 
algorithm (prior models worked just fine) and

2.

super cheap micro cassette recorders. Some of them didn't have adequate signal 
to noise ratios to begin with.


 The cable worked with cassette recorders, olympus i400 mico cassette,  digital 
dictation recorders, Music Cds (with programs on it), tiny mp3 player/recorders 
(like the Iriver T30), and audio ports on a computer, etc. If you make a 
recording of the audio of a m100 program file and want it to be in mp3 format, 
I would suggest a rate of 196k. Lower rates will work, but 196k is a sweet spot.

The audio coming from an m100 is line level. Some recorders only take mic 
level. You will need a a line level to mic level passive attenuation circuit.


As for the original post in this thread A TON of m100 programs could be 
placed on an iriver T30 or equivalent and played back with the names of the 
files on it's tiny display. It could also record the files, but no fancy names 
unless you edit the device. Something small like that would need fresh 
batteries when recording, but it works.

Okay, my wifi232 adapter arrived today.

it's a lot smaller than I expect. It seems smaller than my BlueM, but is
probably about the same size. I'll do a comparison later. I'm really
excited about trying to get on the internet with it.

It also has a built-in web server, so I'm excited about messing with
that, too.

It has a mini-USB plug for power.

Paul Rickards says it requires 5v at a minimum of 100mA.

What I'm wanting to know is if it's possible to connect it to a cell
phone battery backup device?

The kind they sell at Walmart for $10. I've several of them sitting around.

One of my battery backups says that it outputs 5v 2.1A.

I even have a battery adapter that takes 4 AA cells and connects via USB
(but I have no idea what voltage/amperage it uses, and I don't have a
multimeter anymore). I've used it to recharge my cell phone before.

If I have to plug the Wifi232 into the wall or into a PC, it kind of
ruins the portability factor.

cool trivia: Paul Rickards' business card is included in the box, and it
looks like an old-fashioned punch card.
