I was thinking the other night about potential operating environments for the TI. My mind has always wandered around the idea of GEOS (a disassembly of which is available from here) on the TI, but most times I fall across CP/M as I know it was/is available for various CPUs in the form of CP/M-86 (8086,) CP/M-80 (Z80, 8080,) and CP/M-68k (68000.)
From this thread I understand there was a CP/M card for the TI which incorporated a Z80, as was the way back then to partner a Z80 with the existing computer's CPU.
Then my mind wandered around the Atari ST and how Atari was going to use CP/M originally but instead went to GEMDOS, the source for which was apparently released some time ago.
Now when considering disk operating systems for the 4A I think of:
1) GEOS (disassembly available)
2) CP/M (source available)
3) GEMDOS (source maybe available)
What about CP/M-9900? Has anyone ever ventured into the realm of compiling CP/M for the 9900? The source code is available at the Unofficial CP/M Website. A bit beyond my experience but I would love to give it a shot sometime.
The question, of course, will be, what is the value of such projects? Really, what would GEOS or GEMDOS on the TI provide? How would CP/M be useful on the TI? None of these would have readily-available software, which was at least the core idea with CP/M-80 and a Z80 CPU.
Well, why do we climb the mountain?
