Vinegar.  You will find many videos about cleaning up leaking batteries on 
YouTube.

This is a common problem with vintage computers.

Re: [M100] RS232 IO BASIC question

[Ron Lauzon]

You can have the COM port open for both input and output at the same time.

I did a TPDD-ish experiment a while ago and wrote some BASIC programs to work 
with it.

Re: [M100] Hello......!

[Ron Lauzon]

My understanding is that the NADSbox was superceded by dlplus and later 
LaddieAlpha.

I created a recipe and software to use a Raspberry Pi 0, battery and display to 
create something similar to a NADSbox (i.e. you just hook it up and it works 
like a TPDD).  https://github.com/rlauzon54/pi-tpdd

But you can run LaddieAlpha on your own PC or mComm on your phone/tablet to do 
the same thing.

Re: [M100] Just got my 100

[Ron Lauzon]

Owning vintage computer equipment is really no different than owning a vintage 
car.

You can't go to the local auto repair shop to get it fixed because they won't 
have the tools or the parts.
Speaking of parts, you can't go to your local auto parts shop because they 
don't have the parts (for the most part).

You will have to learn how to maintain the electronics to keep it running, just 
like someone who owns a 1931 Ford Model A will have to learn how to maintain 
the car.

That's the reason why I won't even consider buying some vintage computing 
equipment: I don't have the skill and I don't have the time to learn.

But in working with vintage (and retro) computing equipment has taught me a 
great deal and expanded my knowledge about computers in general.

But if you are unwilling to acquire the knowledge, you would probably be better 
off using modern hardware with software emulators.

Re: [M100] Warning: Not a(n) M100 but a PC-2 question.

[Ron Lauzon]

The batteries only give the extra "oomph" to run the solenoids when printing.

But it's possible that the printer is reporting batteries too low.

Note that you can use a more powerful AC adapter to power the printer/PC-2.  I 
have a 2A one for my set up.  Then you don't need the batteries at all.

Re: [M100] Looking for TRS-80 Catalog Item 26-3612

[Ron Lauzon]

Ya, when I had my PC-2 RS-232 interfaces apart to replace the batteries, there 
was a good amount of stuff in it.  It certainly wasn't a simple "run some lines 
from here to the serial port".

The ROM probably includes some PC-2 commands.  I know that when you plug the 
RS-232 interface in, BASIC gets some extra commands to deal with it (like set 
baud rate, etc.)

Ah, yes, the PC-2 RS-232C interface.

I have an extra one that I can sell to you.  I'll have to look to see if I have 
all the brackets for it (I might not), and I think I can scare up a power 
supply for it.  The ones that I have have had the batteries replaced.

Nice idea.
This is how many people have done software libraries for the TRS-80
Pocket Computers.  In nearly all cases, the cassette interface was the
ONLY way for a Pocket Computer to save/load stuff to an external
device.

But that's the first time I've ever heard the term "quickly load" in
conjunction with the cassette interface of any computer.  8)

If you use an AC adapter with more amps (like 2), you can run the

You have to place the order over the phone.  I picked up a few sets

Re: [M100] TRS-80/Tandy Pocket Computer

[Ron Lauzon]

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.

Re: [M100] SD2TPDD Project

[Ron Lauzon]

Interesting.  You are trying some options that I wasn't aware of when
I did my experiment.

Keep us posted as to how this is working for you.

I think I have all the hardware needed to test this out.  If I can
make some time, I can test it out.

[M100] mcomm problems

[Ron Lauzon]

I'm playing with mcomm 1.8.1 on my Tandy 102s and I am encountering
some problems.

When I attempt to load a tokenized BASIC program, it's not loading
correctly.  When I list the program, all I get is something like:

17474 EN
16

I've tried on 2 different M102s.  I am using TS-DOS as the client (one
from REX and one from a TS-DOS ROM).

I am able to see all the files in TS_DOS and I can load non-BASIC
files just fine.
I have verified that the files that I am loading are tokenized BASIC files.

Any ideas?

Re: [M100] T102 hardware flow control

[Ron Lauzon]

Cool.  Thanks!

I did get it to work by setting the WiModem232 to 38400 BPS before
firing up HTERM.

But I prefer a 19200 BPS version of HTERM.  I really don't have any
other computer with a serial port on it, so if I messed up a setting
in the WiModem232, I'd have to do a full reset on it to fix it.  With
a 19200 BPS version of HTERM, I can use TELCOM to fix the WiModem232
setting.

Re: [M100] T102 hardware flow control

[Ron Lauzon]

Then that would explain my problem.

OK, so I'm trying HTERM out.  I picked up a copy of it from here:
http://bitchin100.com/wiki/index.php?title=HTERM#Loading_HTERM
and followed the install instructions.

I don't get any "beep" when running HTERM.CO, but I just get an empty
screen and have to hit the reset button to get back to the menu.

I installed HTERM.CO by hooking my TPDD2 up to my PC and using
TpddTool to copy it to a diskette.
I then used TS-DOS to copy HTERM.CO from the TPDD2 to my M102.

Re: [M100] T102 hardware flow control

[Ron Lauzon]

I'm using the standard Telcom program.

The big file test won't show me anything new.  I see the problem
simply asking the WiModem232 for information (i.e. "ATI" command).
The higher the BPS, the sooner I see the garbled output.

[M100] T102 hardware flow control

[Ron Lauzon]

So I'm playing with my WiModem232 and I still cannot get to to
communicate reliably at any speed over 600 BPS.

I have hardware flow control on the WiModem232.  My RS232 monitor
(https://gglabs.us/node/1077) shows the control lines active.

The question I have is:
Is the T102's hardware flow control RTS/CTS or DTR/DSR?  The
WiModem232 documentation says this:
"The WiModem232 can be configured for hardware handshaking. Typically
this will be RTS/CTS, but some devices (like printers) may need DTR or
DSR instead. By default, RTS/CTS handshaking is enabled and there is a
bridge between DTR and DSR."

He made the WiModem232 configurable, but to change this, I'll have to
get our my soldering iron and I don't want to do that if I don't have
to.

Re: [M100] WiModem232

[Ron Lauzon]

I got my WiModem232 yesterday and had some time to play with it today.

1. I could not get it to communicate reliably at any speed > 600 BPS.
Anything over that and it dropped characters.  As far as I know the
cable I'm using is a straight through 25 pin male to male cable.  So
hardware flow control should work.
2. My WiFi's password "Was a really long passphrase, eh?".  I had to
shorten the passphrase to allow it to connect to my WiFi.  It refused
to connect with my long password with spaces in it.
3. Network scanning didn't work.  Known bug that a new firmware will
fix, but you have to get it connected to your WiFi do to that.

After figuring out those things, I did a quick connect to a random
telnet BBS and it worked fine.

Re: [M100] Tandy 102 Text question

[Ron Lauzon]

This project 
<https://zx81keyboardadventure.blogspot.com/2017/08/model-100-micro-sd-card-reader-mytesed.html>
gave me the idea to try my project.  He is using 1200 BPS as well.
But, strangely, he's using 7 bits and ignoring parity, as well as
turning off XON/XOFF.

I'm in control of what the Arduino sends, so I know it's not sending
an XOFF.  Now that doesn't mean that something else is happening and
an XOFF is getting sent to my T102.
I'm running on the assumption that the Arduino, being much newer
hardware, should have no trouble keeping up with the T102.  I think
that's a correct assumption, but it's still an assumption.

If I spent the resources to get an RS-232 monitor, I might be able to
see which end is having the issue, but it's not worth it to me right
now.

Re: [M100] Tandy 102 Text question

[Ron Lauzon]

Well, the DTR/DSR loopback became moot.  Both of the shifters that I
had that supported DSR/DTR failed.  I couldn't get them to work at all
(even without the DTR/DSR settings).  I think I messed them up a while
back.

But it seems that 1200 BPS will work off the internal Mega serial
ports with the known good shifter that I have.

So this project is a success.  Thanks to all of you who helped me out.
I appreciate it.

My project is documented on github
(https://github.com/rlauzon/MemoSaver) if you want to see what I did.

It was a simple project, but it helped me pass the time until I start
my new job on Monday.

Re: [M100] Tandy 102 Text question

[Ron Lauzon]

I'm trying to avoid making a custom cable.

The shifters that I'm trying to use have jumpers that allow me to
control the DSR/DTR on both ends of the connection so that I don't
need to make a custom cable.
Right now, the jumper is set to loopback on the M100 side of the connection.

Re: [M100] Tandy 102 Text question

[Ron Lauzon]

I located the pin numbers for the Mega's serial ports.  It looks like
Serial1 and Serial2 conflicted with the SD card shield.  But I did get
communication on Serial3.
Unfortunately, it has the same problem.  Fails after the same number
of chars sent.

So not much of an improvement.  But at least I got rid of the
SoftwareSerial library from my project.

I broke out the RS-232 shifters that supports DSR/DTR and set them up
to loopback on the RS-232 side, but I couldn't get them to work.
I have a couple of things I need to check, but I think those shifters
simply don't work.

I remember looking into that a while back on a previous project that I

I'll look into that as well.

I don't believe that the RS-232 shifter that I am using for this
supports DTR/DSR loopback.  I'll try a different shifter tomorrow and
see what happens.

Thanks.

[M100] Tandy 102 Text question

[Ron Lauzon]

Here's the setup I'm going to talk about:
Tandy 102, serial cable to my Arduino with an RS-232 shifter.  I'm
using the SoftwareSerial library to interface the RS-232 shifter to
the Arduino via the Arduino's TX/RX pins - as opposed to using the USB
cable.

Software-wise, this is pretty simple.  I'm just writing a text file in
the Text app and saving it to COM:98N1E

Here's my frustration.  No matter what I do, the 102 stops sending
after about 80 bytes.

The only way I could get it to work was to reduce the speed to 300 BPS
(and, of course, saving to COM:38N1E).

Keep in mind that this is the 102 sending to the Arduino.  I find it
difficult to believe that the Arduino couldn't keep up.  And when I
tried other BPS, it stopped in exactly the same place: at 80 bytes.

The 102 never showed an error message.  Everything looked like it
worked fine on that end.  But the rest of the text file never appeared
on the Arduino side.

The Arduino set up doesn't support hardware flow control.  So I
thought that enableing XON/XOFF would make sure that the 102 didn't do
that (No, I didn't see any XON/XOFF characters on the Arduino side
either).


Is there some sort of strangeness in the 102 that turns some sort of
hardware flow-control on for speeds > 300 BPS?  Or did I miss setting
something?

If there was a problem with one side keeping up, I expected to see
dropped characters, not communications just stopping after 80 bytes.

It was an eBay ad.  I remember seeing it too (more than a few times).
The guy wanted way too much for the set up.

Re: [M100] LaddieAlpha on Raspberry PI 0

[Ron Lauzon]

Must be another bad Microsoft error message (I have to deal with those
all the time at work).

While checking out this page:
http://blog.bennymichielsen.be/2016/03/14/getting-up-and-running-with-mono-and-raspberry-pi-3/
I found this:

It turns out installing mono runtime doesn’t quite get you all the
bits you need. You need to run the following command:
sudo apt-get install  libmono-system-core4.0-cil


And that's what it took.  Once that was installed, it worked.

Thanks.

[M100] LaddieAlpha on Raspberry PI 0

[Ron Lauzon]

I'm doing some experimenting with a Raspberry Pi 0 W.

One of the experiments is using the Pi as a TPDD.
I got DLPlus working, but I wanted to try LaddieAlpha.

The mono install went easily.  I downloaded LaddieAlpha from
http://bitchin100.com/files/linux/LaddieAlpha.EXE
and ran the command
mono ./LaddieAlpha.EXE /dev/ttyUSB0 6

But I get an error of:

Could not load type 'LaddieCon.LaddieIoWin32' from assembly
'LaddieAlpha, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null'.
  at LaddieCon.ClassMain.Main (System.String[] args) [0x0009a] in
<3010b33c0ccc4834a4709b1aced20042>:0

Did I miss something?  I've checked
http://bitchin100.com/wiki/index.php?title=LaddieCon#LaddieAlpha
and I didn't see that I had to install something else to make this
work under Linux.

[M100] Virtual cassette idea

[Ron Lauzon]

I'm running an idea through my head and I'd like to bounce it off you guys.

The idea is to create a virtual cassette recorder/player.  Possibly
for my T102, but also for the pocket computers that I have.

I've found this
(https://www.tindie.com/products/masihvahida/audio-stereo-sound-player--recorder-module/)
which is pretty much done.  I would just have to hook up an RS-232
shifter and sacrifice a cassette cable for my T102.

I've also found this
(https://www.tindie.com/products/masihvahida/soundduino--audio-shield-for-arduino/)
that I'd have to do my own programming for as well as add an Arduino.
This one also has normal 3.5mm jacks, so no cable sacrifice needed.

The idea would be that I could use CSAVE and record a WAV file onto
the SD card and use CLOAD to read it back in when I wanted.  I've seen
this offered as a way to load software for pocket computers using
their cassette interface and the sound inputs/outputs on a PC.

Re: [M100] programming question

[Ron Lauzon]

No.  A War Dialer was something that called many phone numbers looking
for a carrier (or something to show that there was a computer at the
other end).

What he'a thinking about is one of the full-featured terminal programs
that we used to use.  Many of them had some sort of scripting language
that let you automate tasks.

In theory, if you had something like a Hayes modem set up, you could
write a program that opens the serial port for read and write, then
send commands to the serial port and read the results.
So it may be possible, but not through the TERM program on the M100.
You'd have to write code for it.  I did something similar when I wrote
up my clients for RDOS.

Re: [M100] Wifi232 serial wfi modem

[Ron Lauzon]

Using a Rasp Pi is actually pretty easy.  Hooking up an RS-232 shifter to
the on-board serial port lets you use Model 100 as a console to the Rasp Pi.
http://www.savagehomeautomation.com/projects/raspberry-pi-installing-a-rs232-serial-port.html

>From there, you can pretty much do anything in Linux - as long as it's text
based from the command line.

I've been toying with the idea of doing some retro computing things, but
using the Rasp Pi as the host and hooking up an old PC (or a terminal, if I
can find one for a reasonable price).  With people like Eric S. Raymond
"rescuing" the old text-based games (like Super Star Trek and Advent(ure)),
you can still have a fun time, and pretend that you are young again.

Re: [M100] Writing to a .ba file

Yup.  That's pretty much all I want to do.

It's a little more than just read from COM write to .BA file since I
have a protocol around it for handshaking, etc., but in essence, it's
just reading from COM and writing to a .BA file.

Re: [M100] Writing to a .ba file

[Ron Lauzon]

Ya, that's what I'm (trying) to do.  It's been 30 years since I've had
to deal with assembler, so I'm not willing to do that.

But, otherwise, it works.  The new project is on:
https://github.com/rlauzon/rdos

It implements a sort-of-TPDD protocol and the client programs are
written in BASIC.
But it does work and works quite well so far.

I removed the features of the TPDD protocol that I didn't need (like
format drive and drive status) and changed others ("previous file" is
"change directory" in my project).
I allow you to use all 24 characters of the file name field (for
naming the file on the disk - you still have to deal with the file
name limitation on the M100).
It will "boot" the loader program by doing a LOAD "COM:98N1D and
pressing a button.
Once the loader program is there, you can load the save, list and
utility programs.
I implemented directory handling, so you can use a nice, big SD card
and subdirectories.

I've booted up from a hard reset on my T102, loaded up all the
programs, and played for a bit.  I still need to really kick it
around, so it's in alpha test right now.

About $85 in hardware (I had the 32 GB SD card, drive activity LED,
boot button and 9-25 serial cable laying around).
I only needed to solder the headers to the SD Card shield.  Everything
else was just plug/play.

Ya, that's what I want to do.  The .ba I want to write was originally

I just don't know how "special" they are (sort of like the
restrictions on the .co files).

My latest project is rather successful, but when I try to

open "file.ba" for output as #1

I get an error.  Based on the research I've done so far, writing to a

Re: [M100] Getting a REX for Tandy 102

[Ron Lauzon]

I have the hardware working.  You have to make your own cable.
Right now I am debugging the code.  I'm getting some interesting
not-quite-spec requests from TS-DOS.  But things look promising.

Right now, hardware costs are:
Arduino Mega - $46
MicroSD shield - $15
RS-232 shifter - $14
(You can get everything at sparkfun.com)

I had the wires, serial cable and LED (drive in use light) laying
around, so there was no cost for me for those parts.

It will require some simple soldering - beginner level stuff.  You
need to solder the headers on to the MicroSD shield and RS-232
shifter.  And you'll need to take apart and adjust the serial cable (I
just cut mine in half and changed the wires there).

The code will be open source.  I have it in github right now:
https://github.com/rlauzon/arduino-tpdd
along with the documentation that I've created so far.

Re: [M100] Model 600 telcom

[Ron Lauzon]

>From dl.c (Desklink for Unix):

if(st.st_size>65535)
{
normal_return (0x6E); // file too long error
break;
}

So the 64K-1 limit is no surprise.

Re: [M100] We don't bite (often)

[Ron Lauzon]

I came to my hobby simply because I got on a vintage computer kick.
The very first computer I ever used was a TRS-80 Model I Level II
(upgraded from Level I).
After high school, I purchased a PC-4 with some graduation money and
that "computer" lasted me through college and into my profession -
Computer Science.

When the Model 100 came out, I wanted one, but was too poor to get
one.  Now I can get one - and I did.  I picked up a nice Tandy 102
from eBay.

Now, I'm going to enjoy remembering the programming style of my youth
and have fun using my Model T to do some things that it was never
meant to do: like being a console for my Raspberry PI web server.
