I am having problems running CP/M 2.2 software on the DEC Rainbow
and could use some help from the net gurus. Basically, the software
was written on 2.2 machines and gets brain damaged when run on the
Rainbow. I assume that the problem is due to some change or lack of
support by the Rainbow's CP/M-80 for certain BDOS calls.
Firstly, just for the record, the software utilizes the following
BDOS (0005h) calls: 1, 2, 3, 4, 5, 6, 9, 10, 11, 12, 13, 14, 15, 16,
17, 18, 19, 20, 21, 22, 23, 24, 26, 28, 29, 30, 32, and 37 (yes,
it's a rather large program). Would anyone be so kind as to verify
if the Rainbow supports these? The manuals I have access to do
not contain this information. Also, does DEC mention any changes
in their operation as compared to CP/M 2.2.
Does anyone know, in general, how compatible DEC claims to be (or
really is) with 2.2. Many emulators do a pretty good job, others
don't. I guess DEC's doesn't.
Additionally, does the BIOS support access to the jump table for
I/O (const, conin, conout, listout, listst, reader, punch) and
the select disk (SELDSK) function?
I'd appreciate it greatly if someone took the time to assist me
with this brain buster. Thanks in advance.
