In regard to this topic, I have an Apple Z80 card that
seems to
connect to the board via a wide rubber-covered interface, one end on
the card the other to the board. It has the Z80 cpu plus an AMD
2716IDC Applicard Copy chip too. Dated 1/85. Couple of questions:
(Questions are basic. I'm a writer not a techie, per se.)
1. Where is this card supposed to go? Does it sit outside the case or
connect inside somehow? The front is sloped as if it would sit on the
board under the lid plus there is a small 'leg' on the card with a
hole in it as if to screw onto something.
I can't quite make out your description but generally you would plug the
CP/M card into slot 0 of a ][+, and I think slot 3 of a //e.
2. As I also have lots of Apple CP/M disks, what is
the routine for
booting? From the drive? Key routine? Holy water?
Just stick it in the drive and reboot. The boot sector on the disk will
automatically activate the CP/M card.
3. Which slot would the card use? I assume it has
memory on it and
bypasses everything on the mboard except the drive but maybe not.
Nope, it uses the same RAM as on the motherboard. Some cards, like the
Premium Microsoft Softcard //e, provided CP/M, 80-columns and an
additional bank of 64K for the Apple //e.
Also, general interest here, I have at least two Apple
clones that
have both the Apple cpu on the board and a Z80. Not sure if this is
common in the States or not as there seems to be a lot more clones up
here in Canada. One of these clones has what looks like a set of
connectors for another type of floppy plus the regular Apple floppy
driver card.
Some clones came like this. Apple clones are something that I wish I was
more serious about collecting as I've passed up a few. They have odd and
interesting variations that make them unique and collectable in my
opinion.
