Re: [M100] Any writers still using an M100?

[Mark Wickens]

I think the issue here is down to what kind of writing you do. For Tech
Blogging it becomes very inconvenient to use an unconnected device as you
constantly want to be referring to links and media. For creative writing or
novels it would be a completely different matter.

When I decided to use DEC's VAX/VMS terminal based word processor ALL-IN-1
(well, technically WPS-PLUS embedded in the office automation suite
ALL-IN-1) I faced many of the same challenges you would attempting to write
on a Model 100 - I ended up creating a simple set of conventions that
allowed me to embed links into my pages that were then post-processed into
HTML pages. Here is a description of the process:
http://www.wickensonline.co.uk/retro/documentation.html - in this case I
'rolled my own' solution because I wanted to do the processing on VAX/VMS
but there are however many standards for embedded markup into text files
that could be put to good use. One of the leading examples would be
markdown: https://daringfireball.net/projects/markdown/

Any convention employed for text on a M100 family device would need to be
very straightforward. As much as I love TeX I wouldn't want to be
attempting it with such limited screen estate!

Kind regards, Mark.

[M100] Tandy WP2 Memory Expansion chips HM628128BLP-7

[Mark Wickens]

I forget what you do with these (replace an existing memory chip or 
insert in an additional socket) but they increase the stock Tandy WP2 
memory. IIRC they are static RAM chips.


I have three of them HM628128BLP-7 free for the cost of postage from the UK.

I think i have a couple of expansion chips for the wp2 left over if anyone

Re: [M100] [UK] Tandy Model 102 and 200 for sale

[Mark Wickens]

I seemed to miss Bruce's reply directly, somehow.
Yes, I appreciate that the 102 would make a useful tool. I dare say 
there is some logbook software out there too :)


I have a Panasonic Toughbook in bits at the moment as the CCFL tubes in 
the display finally packed in - what a job extracting them was! I have 
some new ones on order and hopefully, if I don't bodge it, the machine 
will be back in action. There is no comparison that can be made between 
that and a model 102, but it is a useful tool with it's all-light 
conditions display. However, it is heavy and battery life isn't great. 
It does have GPS and Mobile WIFI built in however, with a nifty little 
antenna!

   ABOUT RETROCHALLENGE

In a nutshell, the RetroChallenge is a loosely disorganised gathering of 
RetroComputing enthusiasts who collectively do stuff with old computers 
for a month.


The event is very much open to interpretation… individuals set there own 
challenges, which can range from programming to multimedia work; 
hardware restoration to exploring legacy networking… or just plain 
dicking around. It really doesn’t matter what you do, just so long as 
you do it.


While the RetroChallenge has its competitive side, it’s not really a 
contest… it’s more like global thermonuclear war — everyone can play, 
but nobody really wins.



   COMPETITION RULES

1. Retrochallenge commences 1st October 2016 and runs until 31st
   October 2016.
2. In order to qualify, computer systems must be vintage (this used to
   be defined as 10 years old, but typically ‘vintage’ is older than
   that now – don’t expect to be accepted if you are using a box
   capable of running Windows XP for example!). Exceptions will always
   be made for exotica!
3. Gaming consoles and PDAs qualify if they were made in the previous
   century.
4. Where appropriate, replica hardware and emulators may be used.
5. Entrants are responsible for adequately documenting their projects
   and submitting occasional updates during the contest, preferably
   with an announcement on twitter with #retrochallenge.
6. Projects may encompass any aspect of retro-computing that tickles
   the fancy of the individual entrant.
7. Winners will be carefully selected and adulation bestowed.
8. Have fun!

Re: [M100] ROM Available

[Mark Wickens]

I also ordered some of the PCBs a while back, built one then realised I
couldn't use it in a Model 102. However, since then I have obtained a Model
100 but it has substantial corrosion to the mainboard and keyboard
connectors so it may be a while/never before it is functional again.

Hi

I have a Model 102 with serial number 908300060. I also have a Model 200
to try which sports the prohibited sticker also. I recently acquired a
non-functioning Model 100 which I'll get round to fault-finding in
January and an NEC which I haven't done much with yet (the down-cursor
key is non-functioning and appears to be a custom key compared to the
rest of the keyboard together with all the cursor keys).

I am interested in the possibility of implementing a protocol that is
resilient to compression algorithms so any additional information would
be gratefully received. My idea was to use the Model 102 to blog about
my retrochallenge from various weird and wonderful locations with only an
acoustic coupler and a mobile phone. I would require access only
'back-to-base' so could implement something custom at the other end too.

I have just bought some 8-pin DIN connectors so am going to wire up my
own direct cable and attempt to call out with that. I did receive a
cable with the Model 200 but it is in poor condition and I'm not
entirely convinced that it is wired up correctly.

Which leads to a question - if the cable is wired up with two
connections only to the phone connector would you expect to have audio
feedback provided within the Model 102 whilst handshaking? My
experiments attempting to get this cable to work have involved using a
separate phone to dial and initiate the connection.

I may also look into the rom of this Model 102 and see what there is
around the dialing calls for example. This is the bit that seems to be
missing from my ROM.

Regards, Mark.

Re: [M100] No modem in my Model 102?

[Mark Wickens]

Thanks for the responses - as it happens it was more down to me not
entering the modem stat specification correctly into the terminal program.
Once I got something accepted then I heard the 'ping' of the relay to
switch in the modem circuit and was able to hear the familiar screeching
via the acoustic coupler.

I haven't got anything to work reliably however which is a shame but it was
a long stretch. I bought a 'retro' bluetooth handset and paired it with my
mobile phone. There may be still some mileage in it but I suspect there are
too many compression algorithms in the way.

I may need to resort to a direct connection cable or external modem instead.

Mark.

[M100] No modem in my Model 102?

[Mark Wickens]

This is a bit weird but when I use TELECOM with the switches on the 102 set
to ACP and ORIG and an acoustic coupler attached I am unable to specify a
STAT of M711E for example.

I also don't see the function labels mentioned in the manual.

Is it possible that my Model 102 has had the modem functionality disabled
being a UK model?

It's all a bit weird! Unless for example the DIR/ACP  switch isn't
functioning correctly - presumable even with it set to DIR you would expect
to see modem related function labels such as F2 being call.

My understanding is that the 'M' in the STAT string means use the PHONE
connection and a number means use the RS232 connection.

Regards, Mark.

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

[Mark Wickens]

I'm still not quite sure why all the USB to Serial converters end in 
9-pin male - so you need another cable to connect to pretty much anything.
Is there a reason why a null-modem configuration with a 9-pin female 
isn't the norm? I can't think of one. 95% of people buying one of these 
things probably wants that configuration surely.


Mark.

Thanks for the confirmation Don,

There was suggestion to use two low profile gender changers, one
male/male and one female/female to make it work on with he M100.

The $45 price tag is a bit steep. I'm not sure when it went up but
that was the closest thing I found to the perfect off the shelf

control as the old complink cable did in order to
support programs like HTERM which rely on flow control.

And ftdi is the only way to go on Windows.

Maybe a very small pcb that can be built into a thin
hood shell with a surface mounted ftdi chip and max232?

All that said you could accomplish mostly the same
thing by simply aggregating the proper OTS parts and
software and offering it for sale as a package with
documentation. That way it takes out all the research
and guesswork and that's the real trouble.

Re: [M100] USB "juice pack"

[Mark Wickens]

Yes, it's definitely worth re-iterating that Model 100 connector polarity
is the opposite of most all power supplies you could buy off the shelf
these days. The outside is positive, the inside negative. Having applied a
pack with a cable the wrong way round (guessing rather than reading the
manual!) I felt lucky to not have done any permanent damage - but any
reverse polarity protection should be thought of as a last resort rather
than to be relied on!

I working on a solution that hopefully with provide some benefits:

 * wifi connectivity - either built as a daughterboard to the Model M n 
or via a small external adapter

 * lightweight cross-platform disk server
 * support for TPDD protocol - so using TEENY as the client

Oh, and the cost will be low, if I can get it all to hang together!

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 system. Never could make it work with my OS X
machines. Using a Terminal 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.

Truth be known, while it is fun to use the M100, I've gotten
to like my MacBook Pro, on which I run my entire media
business, and do all my writing. I even use my old iPad 2 for
things like answering this email, though the "screen" keyboard
it isn't much good beyond the alphabet. Too many hoops to jump
through just to get numbers and other characters.

The best solution appears to be those developed by several on
this list, like the NADS box, and a couple of other solutions,
which escape my memory. If you haven't already, check out

[M100] Java based Unicode Converter

[Mark Wickens]

Hi folks

Just to let you know that I've been working on my java-based Unicode
converter and it now works (in test mode at least)

Here is the first result, wrapped in HTML to display correctly:

http://wickensonline.co.uk/static/files/tandy/Unicode/keymap-utf8.html

It is a test file that I put together to try and capture all the possible
Tandy characters in one file (I haven't been rigorous in that sense, I will
also have a test file at some point that is just a straight dump of the
character set.

Looks good in the GNU Unifont fixed-width font.

I'll be putting this together as a java virtual machine extension jar file
shortly so that you can simply load T100/T200 encoded files into an editor
and have them automatically converted to Unicode on-the-fly.

Regards, Mark

[M100] Transferring .CO files to a Tandy Model 102/200 without additional software or hardware

[Mark Wickens]

I get the feeling I might have missed something obvious here, but I can't
seem to quite get there.

My faithful old Dell Inspiron 7500 laptop has just packed in so I haven't
had a chance to try out one of the DOS based transfer programs.

I have successfully transferred BASIC and TEXT files to my Tandy Model 200
but I'd like to be able to install .CO files. Is there a way to do this
using software transferred over to the Model 200 in BASIC format? I believe
BA files can be run to create CO files but presumably that must be done on
the Tandy - is there a PC equivalent tool?

I am currently using minicom xmodem protocol and a small terminal program
MODEM.CO to transfer text files but that doesn't work for .CO files (as far
as I can tell).

Thanks for the help, Mark.

Re: [M100] Fwd: Re: Conversion of Tandy Model T characters after PCfiletransfer...

[Mark Wickens]

OK so I've updated the conversion table to take Comet's comments into
account - they all make perfect sense to me.

I also decided to extract the data in the HTML file into an XML file so
that I could run custom XSL/XSLT templates against it to generate the
conversion table from the XML. I'll switch to the generated conversion
table at some point.

The reason for this was that I started hand-balling a keyboard map file and
found that it was taking me a significant amount of time, but more
importantly it felt wrong having the data then in two places. So after some
head scratching I got the map keyboard auto-generating from the same XML
data file.

At the moment it's a map of the Model 100 keyboard characters, I need to
think a little about how best to generate the T102/T200. It's a technical
problem that I know I can solve but I've run out of steam for today.

It would be great to get some feedback!

The updated conversion table is here:
http://wickensonline.co.uk/static/files/tandy/Unicode/TandyModelTCodetoUnicodeConversionTable.html

The new keyboard map is here:

[M100] Tandy Model 100/102/200 Character

[Mark Wickens]

I've updated the table to include the keyboard keys and modifiers 
(SHIFT, GRPH, CODE) to obtain all characters in the table:


http://wickensonline.co.uk/static/files/tandy/Tandy%20Model%20T%20Code%20to%20Unicode%20Generated%20V1.8.html

I plan on re-creating the NATIVE keyboard maps using the data I have 
now, and possibly include the (much more limited) NEC character set.

Hi Ron

That looks great - I have a PSI PP404 printer (industrial wide format 
dot-matrix semi-line printer) that I'll be sure to plug the Model 102 in 
at some point just to check the 24-pin Epson emulation :D


In the meantime I've been busy tonight. Here is the fruits of my labour:

http://www.wickensonline.co.uk/static/files/tandy/Tandy%20Model%20T%20Code%20to%20Unicode%20Generated%20V1.7.html

The table is laid out with the Model 100 character set Unicode 
equivalents listed first, with any differences in the 102/200 listed in 
the 2nd set of columns. I've done it this way to keep the two bitmapped 
graphics together so it is easy to play spot the difference. Some 
differences are quite subtle!


Without any prior knowledge I believe it might be the case that the 
character set was changed between the Model 100 and Model 102 to support 
more Scandinavian languages. The Model 102 character that I haven't been 
able to make a good guess at is character 204 - it doesn't really look 
like a lower case or upper case i based on the serifs of other letters 
in the character set. Anyone got any ideas what letter it might be 
representing?


When I get a chance later in the week I will add the keyboard shortcuts 
for each of the 255 characters. The table is in HTML format with enough 
meta-data to allow it to be parsed as well-formed XML as the basis of 
any programmed conversion process.


Kind regards, Mark

Hi

I noticed that there are some partial unicode mappings for the 
Tandy-specific characters on the following page: 
http://bitchin100.com/wiki/index.php?title=Unicode_Mappings


I think it would be quite nice to be able to transfer files to a PC 
and have (as close as possible) the full Tandy character preserved via 
conversion to Unicode. Anyone like to second this?


As it happens I have done this sort of work before when converting 
legacy APL programming files into Unicode, so it would be a fairly 
straightforward problem for me to solve in this instance.


On a related note having checked the 'print' library page on the 
club100 site http://www.club100.org/library/libprt.html I couldn't see 
any applications that attempted to allowed the fonts to be printed - 
was there a specific printer model Tandy supplied that was able to 
print the additional non-ascii characters?


I've had renewed interest in this and other Tandy Model T topics today 
as I fixed the broken keys on my Model 200 (by opening up the 
individual key switches and cleaning the internals).


Kind regards, Mark

I've made a start - the biggest time waster for me will be to find

Isn't that the part that's already done?

We made that mapping some time back for HTERM.

Only concern is that the 102/200 is different than the 100.

But I know there's a complete mapping for the 100 at least in HTERM.

Re: [M100] Keyboard issues

[Mark Wickens]

Hi Jessica

I'm in the same boat - I have a '200 with three switches which don't work.
I they can be de-soldered and then taken apart for cleaning, but I haven't
attempted that yet. The alternative is to have a donor machine. I have a
102, 200 and NEC and am not clear whether the key switches are
interchangeable. I do  need to get the '200 sorted, so if you don't get any
other replies I can certainly report on my investigations.

It is here:

Some notes:
* PLEASE keep your RAM backed up in REX just in case of bugs.  I'm not 
aware of any but there could be one or two or several lurking in there.
* works with version-3 z-code files only (this covers /most/ Infocom 
games)

* you will probably need at least 24K RAM installed in your machine
* save files can only be written to/read from the RAM file system
* it doesn't support non-ASCII characters yet
* if a game fails to start, or if saving a game fails, you probably 
don't have enough free RAM
* As-built it works with REX v4.8, and the packaging program 
z100pkg.exe is a Windows executable.  See build.txt for instructions 
to build it on Windows; modify if your needs are different.

Thanks for the reply.

Is that a membrane keyboard you're talking about? I haven't desoldered

 This week from Craigslist I got a nice Model 100 complete with

 The only problem it seems to have is with the display: There are
these

 pretty sure that we have been over this problem before, is it

[M100] Model 102 Option ROM

[Mark Wickens]

I bought some of the M100ROM PCBs thinking they would be usable in the 
Model 102 but it would appear I am mistaken.


The PCB as documented here: 
http://bitchin100.com/wiki/index.php?title=M100ROM


I built up the PCB last night with a 32K 27C256 EPROM programmed with 
ROM2 (using the 'new' holes) and found two things:


1. It doesn't fit flush enough to close the door.
2. When I turned the 102 on I got a blank screen.

I cut the trace as instructed for the 27C256, but later the instructions 
seemed to be a little contradictory as to whether a 27C256 was supported 
as an option ROM only.


Am I right in thinking that the PCB isn't supported in the Model 102? If 
that's the case do I have an option to use 'real' EPROMS (as opposed to 
REX) in the Model 102? Does anyone know if the PCB will work in the 200?


I also remember reading that there was a new, expanded capacity REX in 
the pipeline. Is that available yet? I may take the easy route yet :)


Thanks for the help,

Mark.

My plan is to create an OptionROM so any boiler plate code, guidelines, 
etc. would be most welcome.
I am still planning on exploring the SmallC route, but I've already 
started coding in assembler and am quite liking it :)

Certainly 8085 is a lot easier to get in your head than VAX Macro-32!

John,

Glad to hear it exists. The question I am trying to answer is about the
boilerplate. Looking through a few of the Traveling Software ROMs it would
appear that each one is slightly different. Is this because the interrupt
routines are different for various software used on the ROMs?

Kurt



Maybe, in part. Steve and I found bugs/inefficiencies in Mo's
routines. So we were fixing them.

So I'd say it's a few things:

a) Bugfixes/improvements over time
b) Different ROMs, different names.
c) Application specific hardware interrupt handling (software
interrupts / effectively custom instructions)
b) ISTR there being some nooks and crannies where you could insert
code. So some variability may just be that they have application
specific code packed in between system critical stuff.

[M100] Programming languages for the Model 100?

[Mark Wickens]

Can I trouble the list with a question regarding programming?

What are the options for programming the Model 100 other than BASIC and 
machine code, if any?


My Retrochallenge 2015/07 entry this year will centre around creating a 
custom ROM for my Model 102 and I know I'll make more progress on the 
software if I can code it in language like C. I have been investigating 
the options for generic 8080/8085 code generation with a view to 
customizing the output to target the Model 100 architecture. At the 
moment the most convenient solution looks like it will be a custom 
target for the SmallC compiler, but there are other options which are 
generally CP/M based.


Thanks for the help, Mark.

Re: [M100] Programming languages for the Model 100?

[Mark Wickens]

I can get SmallC running under Linux. This generates a SmallMAC (an 8085 
macro assembler) input source file. I have the source code for SmallMAC 
which is also written in C - I should be able to get that running under 
Linux also.


The remaining steps, as I see them, are as follows:

1. Post-process the object files that SmallMAC genarates into a format 
readable on a Tandy 102 (or at least burnable).
2. Provide enough c-library functions to interface with the hardware - 
screen, keyboard etc.

3. Provide a suitable C startup file.
4. Ideally programs would use suitable sections so that they can be 
split between ROM and RAM.


I have done all this in the past with a different compiler targeting a 
single board 68k computer.
Hopefully the memory overhead would be acceptable to leave enough space 
for reasonable sized programs.


I was wondering if you can call the ROM routines from an option ROM?

Regards, Mark.

Re: [M100] Club 100 Online Ordering and bluetooth question

[Mark Wickens]

Just a quick update - and a thank you for all the suggestions.
In the end I moved to my IBM X60 laptop which, with an ultrabase connected,
has a real serial port. I was then able to transfer data at 19200 via
minicom using the same cable without issue. So the problem appears to lie
with the USB - Serial Converted. I'm sure this is probably old news for
some. I do have other USB - Serial converters, so may see if any of the
others work better under Linux.

In a nod to Retrochallenge I have dug out my EEPROM Programmer and UV
eraser and a few 27C256 ROMS. I have an old Dell laptop that will run
Windows XP - I'll probably need to use that for programming!
