Sounds ideal given the BIOS listing and such.
Ideally there are no undocumented PALs or pure unobtanium
parts in the base hardware. (If the floppy controller IC(s)
are unobtainable, that's OK though. I kind of expect that.)
I wrote you separately. Maybe I have something to trade
for your time if it's possible to get copies.

Now of course HDDs are obscenely cheap. I picked up a
60 GB 7200 RPM drive for US $75 recently.

I used TP extensively (and not just in the bathroom ;)
On a CP/M card on a C64 no less. I really enjoyed that
compiler.

That must have been an early QD (?) drive. Wonder how the
data holds up on those over time.

You'd be amused to hear that Jameco STILL sells that power
supply in their current catalog! Too bad they don't have the
LBB...
