All —
I haven’t posted to this list in the recent past, mostly posting to VCF or the S100 group.
But, I’m trying to cast my net wide looking for some specific things for a project I’m
working on.
I’ve done recreations/clones of two Lomas S100 boards – the Color Magic and the Thunder
186 (
https://github.com/RichCini/LomasBoards). This set creates a two-board computer that
can run unmodified PC-DOS. While it’s PC-compatible, it’s compatible in the Tandy 2000
kind of way. I started work on the Color Magic about 2 years ago, pending reversing the
PALs, which happened this year. The Thunder 186 was much easier to recreate, and thus was
done in a few months.
What this system currently lacks is a mass storage option. Lomas offered a SCSI board
(which added an RTC and 4 serial ports), but copies of the manual and schematics aren’t
known to exist on the Internet. There’s also a great alternative, the Lifeboat SCSI (for
the Z-100 machines), but I haven’t been able to locate the software drivers or firmware
for it (I have a manual which has the schematic and PAL equations).
Finally, I can almost get Windows 1.0 running on this setup, but it needs custom drivers.
I have the drivers from the Tandy 2000 (aka, the "Tandy 2000 MS-Windows
Pre-Installation Disk") which don’t work as-is but I believe could with
modifications. I posted to the Tandy Discord server but if anyone should know of the
existence of these sources, please let me know.
Thanks!
Rich
