Thanks; many turntables of the day did not have the 16 RPM option,
just 33, 45 and maybe 78.
Actual mask ROMs were impractical for most things like this except
large volume applications of several thousand units because of the
setup costs.

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

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.

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

once cut

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'
ports, for instance using the Bar Code port to measure frequency and/or
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

That's what the lengthy discussion with Brian is about; if /OE and /PGM
disables data out then a 27C64 should work.
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

the handshaking issues discussed in another thread.
As you note, there are basically two versions (aside from master/slave etc.

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

You'd have more RAM available, and could easily switch to another

Doesn't Steve's program handle the display part? Hooking the RS-232 receive

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!

As I said elsewhere that point of view certainly applies to systems like
Commodore where everything including loading other programs is done through

IMO the Model T is uniquely different in fundamental ways; the 'system
