This talk about an FPGS style terminal sounds neat, but...
How about a set of EPROMS that will fit into an XT, or AT motherboard that in
combination with standard I/O cards (serial port, CGA video) and will emulate a
standard terminal on power on. Obviously this would require input from the
keyboard and proper coding of the video display memory. I suspect that very
little ram memory would be needed (alternate pages or scrolling memory). Given
that smallish older XT motherboards exist with other "surplus" parts, this
could be an interesting exercise.
For extra credit, add a network interface to make a telnet terminal.
While this may not exactly fit the bill, it could possibly fall into the
"classic" category, expecially if one uses an old XT motherboard and say 256k
bytes of memory (8/9 256k x 1 chips, it was before SIMMs).
Just a thought....

They were used on some MSX home computers, although I have only ever read about them (and seen pictures). I don't think they were commonplace outside of Japan and Korea. They were sort of a cross between tape and disk media; data was written sequentially in a spiral pattern on the disk.

An STDC would be nice and I agree, in some ways perhaps more desirable than
the WDI-II but I haven't seen one come available for a looooong time (YMMV).
I also prefer not to lose CDOS or the possibility of CP/M (although I always
preferred MP/M-II even for single user use).

Well, yes, My M does V... ;-)
But you wouldn't "lose" CDOS or CP/M, just direct HD access from CDOS;
I haven't seen any CP/M drivers for a WDI-II and IMI HD - have you?
If Cromix couldn't run your software for some reason or you want the CP/M
"look and feel" you could always still run off a couple of 1MB floppies and
then use Cromix to archive your files on the HD.
Anyway, just thought I'd mention it in case you happen to run across
an STDC before you find an IMI HD.

Does anyone have experience with these programmable bipolar ROMs
failing after a long period of time? I have an old piece of test
equipment that has 8X300 running the display reading its program from
the aforementioned ROMs and the text info is missing pixels -
apparently in the same place in the same letters.
I am pleased to announce that Hewlett Packard and The Computer History Museum have as
of today entered into an agreement allowing CHM to preserve and redistribute all of the
software (objects and sources) along with documentation for the 21xx/1000 family of
computers for non-commercial use.
The software has been explicitly licensed for use both on simulators and real hardware.
HP has also donated a large collection of manuals and software distributions, primarily
>from the late 80s and forward, which complements what CHM already had from earlier software
releases.
CHM will continue to be actively involved in trying to find all of the earlier software
releases which weren't in the HP archives.

More than happy to assist.
I'm around 10 miles from Huddersfield (Saddleworth). I'll be back in the UK
and available to collect / package / post from Monday onwards.

Austin.
Hey folks,
I've bought a sampler off eBay - Casio FZ-10m, contains an 8086, is
user-programmable (Casio released the SDK, apparently) and is way more
than 10 years old, so fairly on-topic I'd say. I need to get it shipped
>from Huddersfield up to Glasgow. Is there anyone within striking

It will probably go out on CD/DVD in stages as things are sorted out.
There has been a volunteer going through the tape images as I've been reading
them checking the contents and making inventories. I need to check with the
people working on 2000 TSB to see what they might have as well.
We wrote the license so that a sublicensee can redistribute with the
same rights that CHM has, so a CD tree may be possible. I don't think
CHM will be able to handle a click-through distribution on the web any
time soon.
I suspect some subset of the software will be available with SIMH as well.
