Hi Ken,

Absolutely without a doubt my NADSBox goes where ever my M-100 or M-102 
goes. :-)  I have found Markdown to be easier to write on the slabtops, 
just because LaTeX uses backslashes and such that are a pain to remember 
how to generate on that keyboard. :-)


I always want to get the files saved off somewhere and I don't always 
have my desktop or laptop with me, so the NADSBox does the job by saving 
the file to alternate storage.  I don't want to disrespect the other 
solutions that have come after it (BackPack, etc.) but NADSBox was the 
OG, and I for one, appreciate you designing and building it!  Thank you Sir!

Re: [M100] On-device file conversion?

Hi Lee,

I tend to stay with straight text options, such as LaTeX or (more 
recently) Markdown.


With either of those plain-text formats, you can specify bold, italics, 
underline, etc. but it just won't render on the laptop that way.  All 
you'll see there is the plain text, appropriately marked-up.


I played with LaTeX for a while but it was too fiddly; so I use Markdown 
exclusively now.

The program is here: https://www.ncus.org.uk/utils.htm#nc_to_rtf

It got me wondering whether BASIC on the Model T could support something

but it wouldn't be difficult to just use some symbols as on/off 
indicators for these. Would it then be possible to use a BASIC program 
like the one above to create a new file with the relevant RTF formatting 
codes in it? I'm sure you see what I'm getting at here.


Maybe someone has already done something similar? Or there's a better

It would be really helpful as I use my Model T for writing quite a lot.

Hi Brian,

If you can lay down 4 vias in a straight line on your PCB, then you can

As the Molex sockets are no longer made, and as I like making custom rom

programmer without needing an actual original socket.


I happen to have a whole bunch of real sockets, and you can even still 
find some old stock on line.

https://www.dhgate.com/product/for-molex-dip28p-ic-chip-socket-silver-plated/372020519.html

But that's beside the point. They'll eventually be gone and they are 
hardly convenient even now while they do still exist. So I'm still 
always keeping an eye out and trying to figure something out that uses 
more generic always available parts, and not requiring some hand crafted 
custom fabrication, something that anyone can do. But it's a tough problem.


Up to now, I've mostly just relied on limiting to having the board use 
an SOIC chip, which are small enough to fit in the available space, yet 
large enough to make a test clip practical. This is like the old ROMBO & 
MOMBO shown on club100. But that still requires an soic-28 test clip 
which are not exactly common, and not exactly convenient given the need 
to hook up the wires.

http://tandy.wiki/images/f/f8/Teeprom_10.jpg

To get away from the soic test clip, and the limitation of only being 
able to use an soic part, I am currently waiting for shipment to test 
another idea:

https://github.com/bkw777/Teeprom/blob/master/4ROM.md

The connection seems to work well, the testing part is just that my last 
version I had a totally wrong pinout on the programming adapter. So I 
re-did the programming adapter and I can't call it good until I actually 
build one and use it.


It's more convenient to use than the test clip, and allows using any 
kind of parts on the board like that TSOP chip there, not just things 
that they make practical test clips for, and it requires no special 
parts. The pins are completely standard and you will be able to buy the 
pins probably forever while the test clip I think is already only new 
old stock by now. But even this is really kind of a pain. That is a lot 
of real estate used up for those holes, and it sure made routing the 
traces a challenge, and that's just for a simple thing like that with a 
single chip and almost no actual circuitry. The whole board is filled 
with holes and traces just to do nothing but simply provide two sets of 
connection pints for that one chip.


What would be ideal is just have a socket that could use the edge 
contacts instead of needing a whole 2nd set of contacts, but, back to 
the top, not a currently manufactured part...


And finally the point of this email, just now I saw something interesting:
https://lectronz.com/products/flexypin-pack-of-100

Obviously not useful as a replacement socket inside the machine to 
repair a mangled one, but looks ideal to make a programming adapter to 
plug in to eprom programmers.
I'm *guessing* that the pcb makes it reasonably practical to solder the 
pins. I imagine the way it works is when you stick the pin in the slot & 
hole, it holds itself in place from the tension, so you can (I assume) 
stick all the pins in and then solder them relatively simply.


I have a half-baked idea for a 3d-printed clone of the original socket 
with either bent gold plated brass wire like what I use to make dip 
legs, or maybe with a custom ffc that goes inside. In either case the 
plastic part would provide the springy pressure to push the contacts 
onto the module.


Or some other idea using a bunch of pogo pins laying on their sides, but 
it just doesn't seem like a great answer.


But this looks pretty interesting because although it looks like it 
might be a single oddball part made by a single manufacturer instead of 
something standard that anyone will always be able to get, it at least 
looks nice and simple. Just a pcb and the pins. And $6 for 100 pins is 
way better than like MillMax $1 per pin for some of their specialty pins.

Re: [M100] WP-2 and WP-3 conversion script

Hi John,

Oh, the algorithm is pretty clear: the 0x08 character appears instead of 
the last space, closest to the end of line, typically where line length 
is 65 characters.


When converting from WP-2 to ASCII text, I replace the 0x08 with space, 
otherwise the words would run together.


When converting from ASCII to WP-2, I will have to figure out which 
space character is closest to end of line and replace it with 0x08.  The 
character after that would be the start of the next line for the 
purposes of this calculation.


The WP-2 does this dynamically when editing text, and when converting 
ASCII to WP-2 binary/native format.  I'm aiming to perform those 
conversions in linux instead so I don't have to wait around 10-15 
seconds for the WP-2 to do it LOL

Re: [M100] WP-2 and WP-3 conversion script

Hi John,

Re. the 0x08 character -- I'm going to go with "Feature". :-)

When I converted from Plain unix file to WP-2 format (inserted a default 
128-byte header and converted the hard carriage returns), the resulting 
.DO file loaded into the WP-2, but all the text ran together, with words 
splitting across lines even in the middle of the word.


So (for my WP-2, at least) it appears to require the 0x08 characters to 
act as a "soft" carriage return where a space would normally be.  Those 
0x08 characters split the line on the LCD, acting like end-of-line, but 
not a "hard" CR.  So I have some pre-processing to do, to insert those 
0x08 before writing the binary .DO file.

Whatever you did, worked.  No dupes this time.

And I mis-spoke as well -- not all of your posts were duplicated.  It
looks like just some from today were duplicated.  My bad.  Sorry.

Re: [M100] Memory release question

[Bert Put]

Hi Charles,

You may have some data in the clipboard.  Open any text file, then
select one character and "COPY" it.  That should reduce the clipboard
(copy buffer) size to one byte.

Also, what parameters did you give the CLEAR command?  Just "CLEAR" by
itself probably won't do anything.  You probably need something like
"CLEAR 0".  Hope that helps.

Hi John,

It seems to me chaining can only work if you are the last "link" as long
as all the apps that are hooked in also chain... or am I
misunderstanding that?

At least if you are first or at the head of the chain, you can guarantee
that you can pass the event on to the next application.

Re: [M100] overflow

[Bert Put]

It's been a while since I've done 8080, 8085 or Z80 assembler, but you
get an overflow if you have a large value in the accumulator (A
register) and add another large number so the result value won't fit.  I
believe that will set the overflow flag in the CPU.

Re: [M100] NADSBox and WP2

[Bert Put]

Hello,

Thank you to everyone who responded!

It turns out the package containing my serial cable arrived today! It is
a straight female to female DB9 to DB9, as mentioned in most of the
replies.  I plugged it up and it "just worked".  Previously I was using
a similar cable which had only three conductors + ground, obviously not
a full serial cable.  I suspected that to be the problem, and was just
heading off any other potential obstructions while waiting for my cable
to arrive. :-)

I did not even realize there were jumpers inside the NADSBox, but since
I wanted to retain compatibility with my (already working) M-100, I
never touched those.  Thank you also for the reminder about terminal
mode; it's true that it makes it very easy to CD into the directory I want.

So to reiterate: A straight DB9 to DB9 female serial cable worked
perfectly.  It literally plugs up and works.  If you get one, make sure
you get low-profile shrouds so they don't interfere with the WP2 or the
NADSbox.  I got digikey part #367-1145-ND, Manufacturer (Cinch) part
#30-9506-77.

Thanks again, and much appreciated.  What a wonderful community!

Cheers,Bert

[M100] NADSBox and WP2

[Bert Put]

Hello,

The WP2 has been mentioned a few times on this list, and I finally got
one, which seems to be working really well.  I also have a NADSBox which
I have been using with my M-100 and T-102 without issue.

Now I'm trying to get the NADSBox to work with the WP2 without success
so far.  For the moment I'm stuck because my serial cable is not a full
null cable, so I've got a replacement on its way (snail mail is very
slow this time of year :-/ )

My question is: Does there need to be any kind of file similar to
DOS100.CO on the SD card for the NADSBox to work with the WP2?  Or will
it "just work"?  In reading previous posts, it seems the NADSBox will
dynamically switch between M-100 and WP2 modes when it sees the
appropriate packets coming down the line (Thank you Ken!)

Can I also assume that I can just continue to use my existing SD Card
with the M-100 6.2 filenames on it?  Presumably it will just "find" the
files in the root directory when I do a file listing?

Cheers,Bert

No worries Steve,

I got mine off of e-bay and there was another unit available from the

other sellers for units that are sufficiently banged-up to match your

G'day Philip,

Yep, I've read through that section several times in an attempt to
reconfigure the drive parameters on the Kaypro to support a larger disk
on the SD card reader.  But that one is currently beyond me. :-)

That's why I was so happy when you built a 3.5Mb drive on REXCPM.  And
I'll say it again: Thank you, and well done!

In case anyone is interested, I found a Wordstar clone at

This is certainly possible, but I did not have much need to switch user

But you can run other programs and the user area does not change.  Weird.

Re: [M100] rexcpm and mvt100 success

[Bert Put]

Hi Jonathan,

You're welcome.

Re. 4Mb on A: -- I know, right??!!??!!  This M-100 is now more capable
than my Kaypro, which has only 390K per disk.  And more portable :-)

CP/M does offer an alternative to directories: USER areas.  Just type
USER 1 to get to it, and you have 15 more.  Some programs will throw you
back into USER area 0 when they run, so watch out for that.

I Meant to expand on one more point: Your best bet at the moment is to
use TS-DOS or something like that to CD to the directory containing the
file you want to IMPORT or EXPORT, and then jump into CP/M to actually
do the file operation.  This works with the NADSBox, and I assume it
works with other TPDD emulators.

IMPORT and EXPORT currently do not handle moving around in
subdirectories, as Philip has already mentioned. :-)

Hope that helps

Thanks, man!  There's a whole slew of them but I didn't remember them

Re: [M100] rexcpm and mvt100 success

[Bert Put]

Yay!

Congratulations Jonathan, I'm glad my notes were able to help you.
There are lots of key combinations in Wordstar that I just have in
muscle memory so I hardly remember doing it, but here's a few:

Ctl-E: up one line
Ctl-S: left one char
Ctl-X: down one line
Ctl-D: right one char

These all form a diamond on the keyboard that makes it easier to
remember.  I have a keyboard template that fits on the Kaypro keyboard
to remind me of all those.  Maybe you can search for Wordstar commands
for a cheat sheet?

Definitely check out SWEEP for a much better alternative to PIP, and
also D for a much nicer directory lister.  They're all on the wiki.

I used serial transfer as well to copy my initial program over, but I
used my NADSbox, which has been absolutely invaluable. :-)

Again, well done for getting MVT100 working.

Cheers,Bert

Wordstar will not run on 40 chars x 8 lines.  Or at least, not very
effectively.  The program will run but it will basically splatter the
screen with characters.

Your best bet (shameless plug) is to get yourself an MVT100 from Steve
Adolph.  Plug it up to a VGA monitor, configure Wordstar for VT100
control codes and you're off to the races.  Jim Anderson suggested that
a few days ago and it's very easy to do.

[M100] My experience building the MVT100

[Bert Put]

Hello,

>From the outset, I want to thank Steve Adolph and Philip Avery for their
outstanding work on the MVT100 and REXCPM.  The main reason for this
email is to reassure folks that it is not hard to build one of these
kits, even for folks like me who have experience with soldering but not
for a while.  It took me about 90 minutes to assemble the kit, and
probably another hour or so of troubleshooting.  So, a fun evening of
work. :-)

The kit comes with a packing list of all the components and I spent
quite some time making sure all the bits were there.  Of course they
were all correct and accounted for. :-)

I started with the low profile components: resistors and capacitors.  If
I were to do it again, I would solder in all the resistors that were
oriented one way (as in up-down vs. left-right) because I found that the
leads on the solder side were getting tangled up with all the resistors
installed.  Same deal with the capacitors although there are a lot less
of those.  You'll find you have to bend the leads quite a bit to get
them to line up; no big deal, just be careful.

The solder pads on this board are not large; you'll find that you'll be
wicking solder through the hole in the board to make the connection.
The exception is the socket for the PIC; its solder pads are "normal" size.

The voltage regulator goes in next; again, you'll be bending that center
lead to make it line up properly with the holes.  As before, be careful
with it and you'll be fine.

Next goes the socket for the PIC microcontroller.  I found it easiest to
just solder one leg in, then make sure the entire thing is properly
seated, and then solder in the remaining legs.

The larger parts go in last: the jumpers, which had the same problem as
the socket: solder in one leg, then make sure they are square down to
the board.  Then solder in the remaining legs.  Finally, the connectors:
VGA, Composite, etc.

Check your solder connections under a magnifying glass.

At this point I decided to power the board up without the PIC installed.
 I wanted to make sure the expensive blue smoke stayed inside the parts
where it belongs.  A quick check with a multimeter to make sure all the
voltages were as expected on the socket, and I felt confident to shut it
down and with power off, install the microprocessor.

I found that the LED was in backwards; a quick desolder and resolder job
fixed that.

Now for the big moment: plugged in the VGA connector, a PS2 keyboard,
and the power via the USB/Firewire connector, and yes, I could see a
startup message on the screen!  However, I could not get any characters
from the M-100 to show up on the screen, and this is where Steve's
support shines through!

A few emails back and forth and we found that:

1. Make sure you have a color selected in the VGA jumper (I did; I used
green)

2. Don't bother to set the BAUD jumper on the board, but DO jump into
settings and set the baud rate to 19200.

3. Press Shift-F12 on your PS2 keyboard (NOT the M-100) to jump to
settings and set:

  - Baud rate: 19200
  - Invert RS-232: 2 (INVERTED)

   Save your settings and exit.

4. On the M-100, jump into CP/M and Press LABEL, F3, LABEL.
   This will cause REXCPM to divert the console to RS-232.
   I had my M-100 connected via a standard DB9 to DB25 RS-232 cable with
a gender changer on the DB-9 end.

   Keep using the LABEL, F3, LABEL sequence to cycle through the various
options: M100, RS232, CASS.  The option does not take effect until you
press LABEL that second time to exit the setting.

5. On the MVT100 board, MAKE SURE you place a jumper on at least one
RS232 pin; I used Rx-3.  If you don't do this, your RS-232 port is not
connected.
   You will be able to tell if it is connected when you see the activity
LED flicker as you press keys.  Per Steve, a flickering LED just means
that the PIC senses activity, not that it understands any characters.

6. Another way to test is to use TELCOM on the native M-100.  Set the
comms parameters to 98N1E (19200 baud) and start a session.  As you
press keys, you should see the LED flicker and characters appear on your
screen.

All you veterans are probably nodding your heads and thinking: "Yep, we
know all this" :-)  but this post isn't for you (but feel free to poke
holes in my methodology if you want :-)

I hope this helps folks who are maybe a bit nervous about putting
together a kit and troubleshooting any issues; don't be.  There's plenty
of help here on the mailing list.  Good luck and have fun with it.

Cheers,Bert

I do have spellstar here but I never used it.  Let me see what (if
anything) I can do with it and I'll let you know.  To be honest, any
files I put on CP/M will end up on my linux box as LaTeX source, so I

Phil's in Australia (I think) so it might be this afternoon before you

If it is set up in REXCPM, you'll want to check the CP/M STAT command to
set up the LST: device.

Hello,

I finally got some time to assemble my MVT100 and get it going, and now
I have a good console for CP/M on my M-100!  I can get my copy of
WordStar running on it but it is configured for my Kaypro and the

MVT100 and if so, is it available?  I can do it but I want to be sure
it's OK to post before I do that.  Thanks.

Hi Jim,

Well, once again I'm proven wrong.  Sigh.  I'm messing around with user
numbers more and more because I'm *loving* the huge 4Mb disk drive
(Thank you Philip Avery!).

Most programs seem to leave you in the user area that you started in,
but it seems VED40 does not -- it will dump you back into user area 0
when you exit.  This is not consistent; not every program does this, but
those programs that do, always do it.  My long-winded point is that it's
not CP/M system behavior to do this; the individual applications are
doing it.  And of course, to correct my statement that I've never seen
CP/M dumping back to user 0 unexpectedly.  :-)

I've done that before, but as I don't have a VT-100 terminal handy I'll

Hi Jim,

I do not recall CP/M ever dumping me back into user area 0 whenever I
run a program.  On the Kaypro and the M-100 I stay in my current user
area, unless I change it with another USER command.  The documentation
states that behavior as well.

Hi Jim,

Yes, I have a WIKI account now so I believe I can upload them to the
WIKI.  I'll do that in the next couple of days, but in the meantime, I
think you can get them from, if I recall correctly, the "Classic
Computers Archive".

These are the two utilities I copy to every single CP/M floppy that I
have; they are my go-to utilities that I use every day.  Especially
SWEEP, since it handles things like file copies, etc. without that messy
PIP trick that described earlier. :-)

And D.COM is 40-column friendly since it displays the list of files in
two columns, each taking 40 columns, which is perfect on the M-100
screen :-)  There are several versions, each one displays things
slightly differently, and I'll package them all up in one ZIP file.
That way you can choose which one you like.

Re: [M100] User number in CP/M for M-100?

[Bert Put]

Hi Steve,

I'm sorry, I guess I wasn't clear.  I knew that "USER 1" would change
users; I know that works.  I was asking about being able to execute
programs from user area 0 when you are in another user area (like 1 thru
15).  That's the piece I can't seem to get working.

My solution for now is to copy all the txt files that I want to work on,
along with VED40, and that works.  I'll want to keep an eye on the
number of directory descriptors since there will be a bunch of duplicate
files out there. :-)

Thank you!

[M100] User number in CP/M for M-100?

[Bert Put]

Hello,

I was wondering which version of CP/M that this was based on?
I'm specifically looking for support for "user numbers" since CP/M does
not support directories.  My Kaypro runs CP/M 2.2G and 2.2H.  In those
versions, the user number is part of the prompt, such as A0> or A1>.
Also, if you navigate to user area 1 with "USER 1", you can call any
executable in user area 0 in case it does not exist in user area 1.
There are 16 such user areas available, 0 to 15.

I can't seem to find that in the M-100 version of CP/M and wondered if
that was some kind of version difference?  Thank you.

Cheers,Bert

[M100] REXCPM in M-100 - Success!

[Bert Put]

Success!

Thanks to the excellent work of Steven Adolph and Philip Avery I now
have the Model 100 running natively as a M-100 with the UR-II in REXCPM
in one of the ROM slots, and can switch to CPM at the press of a Ctl-C
at any time.  It reports the full 4Mb available.

I started with a M-100 that had an actual UR-II ROM in it.  Then:

1. Removed the UR-II ROM.
2. Took apart the machine to install a new memory backup battery.
3. Reassembled machine, Verified operation: good.
4. Installed REXCPM per the website instructions.
5. Used NADSBox to transfer required files to the M-100.
  - I remembered that NADSBox has a command line interface which worked
well.
6. Followed the instructions on bitchin100.com carefully, and it looks
like it worked.

I also transferred some executables from my Kaypro to this machine and
they work as well:
- D.COM (A better directory lister)
- SWEEP.COM (also known as New Sweep, file operations program)
- Wordstar 3.3, which runs but as we discussed, will not fit on an 8x40
char screen, and being configured for the Kaypro, likes to write a *lot*
of control characters to the screen.

I'm looking through my CPM catalog for other programs to copy over.  I
already know that the Z-80 specific programs are currently not usable,
such as Turbo Pascal and VDE.  So far, the programs that I've got are
working so I'm pleased.  I will definitely look into other full-screen
programs that don't need Z80, such as VEDIT40 :-)

What is the best way to make these programs available to others?

Cheers,Bert

This is not a subject that we should probably have on the list, since
it's not Tandy slab related, but I can tell you it's not just COBOL.
You have to know how to build, submit and run jobs, and monitor them as
you go.  Also, Jay Moseley's MVS distro is good, but is not exactly the
same as the "real" big iron, because of copyright issues.  So you'll get
a good flavor of it but it still won't be the "real deal".  You won't
get to play with VSAM, IMS, or DB2 at all on Hercules, and those skills
are important.  Email me directly if you want to talk more about this
in-depth.

Re: [M100] compile and execute Turbo Pascal (Stephen Adolph)

[Bert Put]

Oh, I can't resist... :-)

Yep, I did COBOL too, busted away from it for a few years, and then a
year ago went back to it.  Fun.  How about some mainframe assembler?
It's been a while but I could probably cobble a program together.

Then there's BASIC, Pascal, C, some C++, Java, not to mention the
various scripting languages, AWK, sed, BASH, etc.

Did some Z80 assembler too, but I never got into the 8080 or Motorola
side of things...

I taught myself Turbo Pascal on a Kaypro 2X and wrote a fairly
substantial system on it.  Re-wrote a scoring system from its original
Dbase II implementation.  Now my primary development language is C on linux.

Re: [M100] European T102 - different!

[Bert Put]

Telecom used to (and still do, I believe) keep a very close eye on each
phone pair to make sure you didn't add more handsets to your service
than you had rented from Telecom (this was quite a few years ago).  They
didn't want anything impacting their central office equipment, and a
modem that was not certified to work on their equipment definitely
counted as that.

Remember too that no dial-up modem in Australia would answer the
Bell-standard tones emitted by the built-in modem, so there was hardly
any point connecting it up anyway.  You could not get the integrated
telephone cord in Australia, and I don't think you could get an acoustic
coupler either.  External modem was the way to go, which opened up the
possibility of going faster than 300 baud!  :-)

Re: [M100] European T102 - different!

[Bert Put]

As an owner of a M-100 while in Australia, I remember that we were
forbidden to connect the built-in modem to the Australian telephone
network.  We had to use an external modem.  I do not know if that is the
same in the UK, but it's quite likely.

Hi Vic,

OK -- I only got one unit so I don't know if RAMPAC came in different
cases. :-)  I'm still inclined to think it's a RAMPAC but I'm certainly
happy to be corrected... maybe someone else on the list can chime in.

In any case, I hope you get it working, and have fun with it!

Good morning Victor and welcome to the list.

Based on the description, that is almost certainly a RAMPAC.  I still
have the documentation for mine but I seem to have lost the device many
years ago.  If I recall correctly, the device is a metal case, painted
black?  These days I use a NADSBox (which uses SD cards) and there are
PC-based solutions that also work very well.

Re: [M100] M-102 keyboard flat ribbon cable

[Bert Put]

Hi,

There's another member, Josh Malone, who has a youtube channel and
explains how to do that on both the M-100 and the T-102.  There are some
very useful hints about assembly and disassembly that you MUST pay
attention to.  Those videos were a great refresher for me.

To inspect the battery is easy on the M-100.  Just open the case
(carefully!) and you will see the battery right there, since the
component side of the motherboard is "up" in this unit.  Check for green
powder on the negative terminal of the battery and the motherboard and
if you see any, get that battery out of there as quickly as possible.  I
was lucky in that it had only just started and there was very little on
the motherboard itself.

The task of replacing the battery is easy enough once you get the
motherboard out of the case.  For the M-100, there are half a dozen
screws holding the motherboard in place, one of them is UNDER one of the
8K expansion RAM modules, so you'll need to remove it to get to the screw.

I recently bought a desoldering gun that heats the pad and uses an
electric pump to suck up the solder -- that worked like a charm, much
better than desoldering braid and manual solder suckers.  I absolutely
recommend it.  You can also try the new desoldering tubes but I don't
have any experience with those.

Another member here runs an online store called arcadeshopper where you
can get the replacement batteries, and a new set of capacitors in case
yours have started to swell or leak.  I'm about to place my order :-)

Hope that helps.  Good luck.

Regards,Bert

Re: [M100] M-102 keyboard flat ribbon cable

[Bert Put]

Thanks Brian for the detailed instructions.  It was the "multiple tries"
that likely did me in -- the ribbon developed a kink that I could not
straighten out.  I happened to flip the cable and noticed that some
metal traces had moved, then I said a lot of bad words and put the thing
away.  I'll leave it alone while I think about it some more before I try
again.

I'm actually wondering what would be involved in replacing that entire
ribbon cable and connector mess with a more sturdy solution, similar to
the M-100?  Surely that would not add so much weight, and it would have
to be better for maintenance?

Hi Keith,

I will take you up on that offer, thank you.  I'd like more than one
since I'm sure I'll manage to mess up the replacement :-)  I'll email
you off-list.  I doubt I can get them any sooner then you, and I'll be
more than happy to pay for shipping and whatever number of ribbons
you're prepared to let go of :-)

Thank you for you offer Sir, it is much appreciated!

[M100] M-102 keyboard flat ribbon cable

[Bert Put]

Hi,

Watching all the recent activity about the bad memory battery
replacements scared me sufficiently to go ahead and open up my M-102 and
M-100 to check them.  I did, and sure enough the battery in the M-100
had started to corrode but luckily with very little reaching the
motherboard, so I whipped that puppy out, and I'll hit up arcadeshopper
for some replacements :-)  The M-100 is back together (minus a battery)
and working great.

The battery in the M-102 looked OK but I think I'll go ahead and replace
it as well.  Cheap insurance.  However, I messed up the re-assembly of
the ribbon cable for the keyboard.  I agree with Josh that they cheaped
out on building the M-102, although it was still working after 30 years
so I guess I can't really complain :-)

I have not succeeded in re-installing the ribbon cable into the edge
connector on the keyboard end.  It turns out that it's difficult to get
a straight-line force to insert the edge.  Some metal tracks on the end
of the ribbon have moved and I'm concerned that if I keep fiddling with
it I'll tear it up even further.  I've left it disconnected while I
think about it some more.  I'm wondering if I can glue the tracks down
on the ribbon or something similar?  The keyboard connectors on the
M-100 are much more sturdy and I had no trouble at all getting that back
together.

Any thoughts about how to proceed from here?  The keyboard ribbon cable
on the M-102 is the only problem at this point.  All the caps in both
machines looked good, no sign of swelling or leakage.

Cheers,Bert

p.s. the REXCPM is going into the working M-100.  That was always the
plan since the M-102 has a REX classic in it.

Hi John,

Let me say thank you for enforcing the rules, since I know how much of
as time sink it is to maintain the server and the the newsgroup.  I
don't particularly care about swearing but I absolutely appreciate
keeping this a "no-offensive-word" zone.

For everyone else, remember we are all guests here.  John's
server/house, John's rules.  Simple as that.

Cheers,Bert

Re: [M100] Troubleshooting M102 (Was: M102, Black Screen, Help!)

[Bert Put]

Hi Alan,

I'm with Jeff on this one.  So far you've shown that you've tested
voltages, cables, even the LCD contrast pot, but you haven't really
talked about the logic side.  You mentioned you replaced all the RAM
(even installing sockets), as well as re-capping the board, but so far I
haven't seen anything to verify that the system clock is running, or
that the CPU is running.

It will be hard to do this without an oscilloscope but maybe you have a
frequency counter or something that you can use to verify the clock is
running, and that the CPU is running?  Jeff's video shows how you can
check for activity on the address and data lines; without that activity
literally nothing will happen on the board.  Good luck.

Cheers,Bert (not Jeff :-)

Re: [M100] REXCPM orders update

[Bert Put]

Nah, I don't trust the M-100 for long term storage, whether it is
REX-equipped or not. :-)  Where my M-100 or M-102 goes, the NADSBox goes
with it, always.  And I make a point of saving off anything I don't want
to lose to the NADSBox.  Having said that, the REX is incredibly robust,
holding on to its contents even after getting dislodged in the option
ROM socket!  So I should probably trust it more LOL

Hi Steve,

I'm happy with a 2Mb unit.  Still much better than 390K floppies on the
Kaypro (even if they are emulated! :-) )

And I'll echo "r cs"'s sentiment -- go enjoy Summer while it's here.
None of this is urgent from my perspective, and certainly not worth

Also,  I'm not concerned about the 8.3 vs. 6.2 filename format since
that is no more difficult to manage than I have now with the NADSBox.
So it's a non-issue for me.

Re: [M100] REXCPM orders.

Thanks Steve, that is perfect!  That right there makes it far more
usable than the "proprietary format -> CP/M disk image -> text file"
solution.

I just realized that the wiki at
http://bitchin100.com/wiki/index.php?title=M100_CP/M exists and if I was
paying attention, I would have got my answer from there! :-)

Thank you for not chastising me to read the wiki :-) :-) :-)
Now the link is in this discussion in case anyone else has the same
question.

Thanks again for your great work, and your patience.  Have a good weekend.

Re: [M100] REXCPM orders.

Hi Steve,

Yes, I mean the CP/M RAM disk, for want of a better word :-)
Does that mean that the files are transferred to SDCard (I have a
NADSBox) as plain files that I could then read on my PC?

I'm contrasting with the SD card floppy emulation on my Kaypro 2X which
stores almost proprietary images on the SD card which must then be
converted to CP/M disk image files on order for me to then get to the
files on the "disk" image file.  I'm just trying to understand how your
(or Philips) solution works.  Thanks :-)

Hi Steve,

Just one last question: Does REXCPM allow you to preserve any file on
the disk to another physical disk using NADSBox, LaddieAlpha, or similar
TPDD software?  If not, how would you recommend achieving that?  Thank you!

Hi Steve,

Ah, I think I see now.  The REXCPM provides the BIOS, BDOS, and the rest
of the CP/M stuff, and the Z80 upgrade only replaces the CPU, and adds a
Z80 CPU, but no CP/M specific stuff.  Is that correct?  Thanks!

Hi Steve,

port rate with LaddieAlpha  I'm thinking to just read in data and directly 
place it into the Keyboard buffer.   Once the packet is read - pause and 
process the Rx data.  Ready to send another command then.You lost me on the

Turns out I don't have a system on which the build fails, so

I noticed in Brian's GNUMakefile, he added the --ldflags option

support, and the error "DSO missing..." usually means there is a
missing library option.

I have added the '--ldflags' to the GNUMakefile on SourceForge. 
Can you do a 'git pull' and see if that fixes the problem?

   Hey Guys,

Okay, I have fixed this bug (in src/file.cpp).  The
de-tokenizer was not testing for quoted strings.  I pushed
the changes to the git repo here if anyone wants to pull it
and compile prior to an official VT 1.8 release:

git clone https://git.code.sf.net/p/virtualt/code
virtualt

Does that include bug fixes from v1.7?


I sent Ken a PM back a while ago describing a bug I
  found, but got no response.


The problem occurs when transferring a BASIC
  program from VirtualT to the PC in ASCII format. The
  bug concerns any BASIC program that uses embedded
  ASCII characters with the value greater than 127d
  directly in PRINT statements. When these characters
  are used (for example, the downward pointing triangle,
  167d A7h), the ASCII character value is not preserved
  in the saved output file, but instead a BASIC keyword
  is substituted. 


For example (+ character is really 167d, input with
  the keyboard sequence [CODE]_ ):
A program containing the line:
11510 PRINT@280,"++";


 is saved in the ASCII format output file as:
11510 PRINT@280,"GOTOGOTO";


I am not sure if the keyword GOTO is the actual
  substitution, as I am away from my "development"
  computer and can verify, but it illustrates the basic
  problem. Likely, as BASIC keywords are probably
  represented as values higher than 127d, and the
  routine in VirtualT to save a file on the PC in ASCII
  format is not setting a flag to track the occurrences
  of the " character pairs and interpret any characters
  within as ASCII characters and not BASIC keywords.


Regards,


Peter

Re: [M100] External Power for T102.....probably asked before....

[Bert Put]

I'm a bit late to the party but I use a 6V lantern battery (one of those
big cubes) and a holder designed for it.  It will last years at the
current draw that the M100 has -- in fact, the battery started leaking
before I drained all the power from it. :-)  No damage -- I removed the
battery from its holder before it could do any.

Cheers,Bert
