I was just digging through the dusty recesses of my basement documentation
corner, and came across a handwritten note from some kind soul way in the
past (actually scribbled on the back corner of another document) alluding
that the main processor does in fact need 32K. However, the same note
appears to say that the IOP can have anywhere from 16 to 32K. Of course, a
hand written note isn't the same as an HP configuration manual :). So it
sounds like IOP memory requirements at least are still somewhat up in the
air.

On a related note, the IOP needs special firmware for the 2000 Access
configuration. The only way you can put those roms into the IOP is on the A2
card, which would mean you have to take the floating point option out. So
does anyone have a reading on which processors need FPP and FP options for
2000 Access, or if either of those options are needed at all?

Thanks in advance!
