Creating a new CBIOS is easy using modern tools. Assuming I can get
the first part done (floppy access on a modern PeeCee), my thought would be
to use 22NICE (the CP/M emulator), DDT and SYSGEN to do it.
Ok, but then what do you use for the BIOS for the target machine? Surely not
the same one that's in that package? This is where I get confused.
I have a tool from Sydex to test the SD capability of
a modern
PeeCee controller. If this passes, then I'm OK. The 22DISK manual mentions
that you can take an XT controller and modify it with an inverter to handle
FM disks.
I'm thinking that part won't be much of a problem for me because of all the
hardware I have kicking around here. Within fairly easy reach are my old
Osborne Executive (SSDD only, darnit!) and a Kaypro 4 which has a 50-wire
ribbon coming out of the box and there's another box with a couple of ST251s
in it that plugs into that. All I lack is someplace to set it up. :-)
