Re: TI-H: TI-89/92 ROMs NOT compatible
What I'd suggest is using a new MAC os hardware emulator I'm devolping. It
has a 200k/100k/50k/25k/1k bus. Every 4 refreshes it receives current
mouse position and keyboard keys, and every refresh it sends out the
current screen. The thing can be fitted into the size of a small modem.
It will let IBM people finally use Mac software at a reasonable speed.
(I've got 7/16 and 20MHz processors working). Hopefully I'll finish it.
Btw, anyone ever tried converting analogue video to digital! If I can
figure out how the plus codes video then I can hack it directly from
there...

Does anyone want SCSI support on the TI92/89? I was diging around my
"treasure" room and found my "hot wired" 512k. Apple sold 200 of those to
special distributiors to demonstrate the 'puter. They thought that
customers would buy a computer if it had 4MB/SCSI/800k instead of
512k/400k...
The neat thing is that steve jobs actually signed the motherboard! not
only the Case! There are about 20 wires running from the CPU to a chip
which connects to a ribon cable and then goes out the battery port thing.
It uses the standard a SCSI controller so...SCSI on the 92! I think its a
NCR.

Just use the arrow keys...
