What ROM and Bios Revision levels do you have ?
This makes MEGA-DIFFERENCE. Osborne originally messed with index registers
in version 1.0 of the rom, and neglected to save the IX and IY registers on
the stack in the bios.  Too make a long story shorter, turbo pascal and
others would not run on the machine, and many rumors spread about cpm3 being
incompatible with 2.2 software. Well, a simple rsx (about 8 bytes) inserted
in the system first will fix this trouble (First in, last out) and allow most
software to run.  Most since programs that modify cpm itself of course will
not run at all.  Perhaps this is what is happening with "Write-Hand-Man".
Please reply if you want the rsx source code or find *any* technical errors
in my account of index registers and the ozzy exec.
