Doesn't look like it'd take much to convert the BASIC NC100 version,
especially if you're only using 5 or 6 control codes.

Is it consistent, i.e. do you always get the same garbled output for a

At a fast glance it looks like bits 2 and/or 3 are being dropped; have you
checked the computer to Pi cable and connectors?

BTW, another tip: if you're sending a text file to the M100, send it
without Line Feeds (i.e. only CR) if possible; that will save time
since there's no scrolling, and that's how the M100 sends files
anyway.

The hardware is capable of 76,800 baud and if the other end supports
it then John's Hterm can run at that speed.
Using XON/XOFF handshaking and minimal buffer size the native apps

It's been a while since I've played with the DVI, but AFAIR not only did it
not do bit-mapped graphics but I'm not sure whether it was 100%
compatible with the entire M100 character set (or maybe I'm hiking about
the printer...)
The screen size issue is taken care of by the DOS extensions for the
Sounds like an ambitious project ;-)
You can send the display data out to a display via the com port and, if you
need the port for something else, even the bar code port; there is also a
terminal driver that is compatible with the M100's screen codes. Have a
look here:
If I have a lot of an IC I leave them in the tubes, but they can be awkward
to ship. For most ICS and even some small parts I prefer the pink
anti-static foam, both the semi-rigid type and the flexible types; on a
flat 12x12 sheet for example they're much easier to store and also to ship
once cut
It is indeed a challenge to organize so much varied info; overall it's
pretty well done but I think John could also put a few more entries in the

Not sure what you mean? What's the bad habit?
The idea of using .BA for plaintext BASIC files and .DO for text documents
made perfect sense in the old days. Keep in mind that a stock M100 can not
transfer binary files such as tokenized BASIC or .CO, so normally all files
transferred would be
There are lots of ways to interface to the M100 aside from the 'normal'

voltage, using the RS-232 control lines as digital I/O lines and of course
the easiest of all, the cassette motor relay.
But the actual details of the

Unlikely, but possible; more likely that Georg's board is revised and only
uses 2 active-low chip selects.

Oops; received this after sending mine.
Writes will definitely fail; I'm just curious whether outputs are enabled
with /OE low and /PGM also low.

Looking at the schematic, are you sure it's 8K and not 16 (27x128)?
Looks standard except for pins 26 & 27

I've played with BT adapters and didn't really have any problems except for
the handshaking issues discussed in another thread.
As you note, there are basically two versions (aside from master/slave etc.
issues): True RS232 that have a DE9 connector and plug riight into the M100
with a 25<>9 pin
That's odd; can't your terminal program just wait forever for the next
dump? If it times out, can't you override that?
It probably won't matter with a small file like this but I've found that at
19200 even TEXT has trouble keeping up when downloading. The M100 doesn't
have hardware handshaking
My head hurts ;-)
Oddly enough, explicitly typing variables (e.g. A%) actually slows things
down a bit.
And yes, the intermediate values can be >32767 as long as the result is a
legal integer.

I don't see where it makes much difference In general in BASIC but in this
case there is a justification for MSB first ;-)
It goes from MSB to LSB because the same routine does 4 or 2 digits
depending on where you enter; line 5 gives the 4 digit address and it falls
through to line 7 which also
Granted, it's convenient to have BASIC built into the system ROM but would
we love it any less if it were an option ROM as it is in a number of
similar machines?
You'd have more RAM available, and could easily switch to another
environment/language, e.g. MFORTH, especially if you have a REX or
Doesn't Steve's program handle the display part? Hooking the RS-232 receive
into the keyboard vector should also not be too difficult but as you say,
what's the point?
I don't recall whether the M100 has it (ISTR that it does) but some systems
have a built-in function, usually CTL-P that echoes
Not too terribly difficult; there are various hardware 'modems' (e.g.
Lantronix UDS-10) that can often be found used for around $30, or there are
a number of software apps that run on (through) another computer (e.g.
TCPSER).
Have fun researching!

A different point of view would call the ROM the operating system, with

When Steve and I were playing with M100 to M100 communication over the
internet way back when, he spent a fair bit of time trying to overcome the
small buffer in the Model Ts but I don't think he could ever get it to work
100%. IIRC reducing the buffer size in the ethernet 'modem' down to one did
Terminal sessions aren't usually a problem unless you're sending a file to
the Model T; manual typing in either direction isn't likely to overrun a
buffer and whatever the T is connected to will probably be able to handle
the data stream.
Even receiving a file is usually not a problem if you're
and 3.5" drives?
