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.
2. As I also have lots of Apple CP/M disks, what is the routine for booting? From
the drive? Key routine? Holy water?
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.
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.
