was the bug in the z80 code or the 6502 code? It would be interesting
to know if my PRORDSK package has the same problem.
It's a bit unclear. Signs are pointing to the DPB and DPH being
incorrectly formed for support of drivers >= 256k. Progress has been
bounded by, in no particular order:
- Real Life Intruding
- My having forgotten everything I ever knew about Z80 and 6502 assembler
- Ditto for CP/M internals
- An inability to figure out how I was once able to build the PCPI O/S
image from scratch.
In one small victory, I was able to successfully assemble and link a
device driver :-). I am closing in on having a build environment,
though, and suspect it's something dirt-stupid that I'm doing/not doing.
What is PRORDSK, btw?
