MORE ON Z-80 CARD!



My Apple IIe is slotted thusly:
1.      Tymac Parallel Printer Card.
2.      Apple SuperSerial Card
3.      VideoCard 80 Column
4.      CP/M
5.      SCSI
6.      DuoDisc
7.      Old 5.25 floppy drives inherited from the EuroPlusses I
had previously used.
Strange to say, the CP/M card was none too fussy where it was
located to my experience but its only insistance was to be able to
boot up from the 1 drive on slot#6.
Once it even seemed OK in #1 but the printer card took precedence
though my printer is lousy (prints, more or less, but won't accept
carriage-return whether in a WP dump, program listing or anything
else, substituting a capital M!).
I had to keep switching the graphics tablet & card between the above
and my IIGS but, with the pre-allocated options (to address the ports)
I am left port/slotless for the installation of other lesser
considered trifles e.g. experimental I/O for DIY robotic projects.
With the CP/M in place where it is, I don't know yet whether there
is going to be a conflict over addressing the game-controller...
I suppose the only thing left is to do the experimental stuff on
the rehabilitated IIE using AppleDos & converting to ProDos when
necessary. Of course you should be able on the IIGS to resort to
the Control Panel but I didn't know whether that would provide
only your options after the next reset: surely the software
should be able to access the system at that level though I don't
think CP/M software (or at least the versions I know!) can do it.
You may well be right about the Z80A & Z80B as regards
incompatibility with the full GS speed but I wondered if a later
generation of Zilog chip has been tried that way....
interesting thoughts.....;-)
