I've been experimenting with ways to get a software library for the Apple IIGS.
ADTPRO is an option (worked well for my Apple II/IIe) but I've discovered there is a special (miniDIN8) cable required for the modem port. It's is not a standard 9 or 25 pin DB socket. Not having a cable I tried using a Super Serial card (SSC), first in slot 2 (the modem slot) then in slot 7 (which can take any card). Slot 2 didn't work at all. I wondered if I needed to somehow disable the built-in circuitry somehow. Slot 7 seemed to recognise the card, but ADTPRO still seemed to hang after transmitting only part of it's bootstrap material.
Anyway, I've decided not to persist with the SSC, even if I can get it working. Perhaps I just should get the proper IIGS modem cord (anyone got a spare one?). But then, maybe I really need a hard disk of some sort. I have a CMD SCSI card and could reformat one of my MAC external drives to a IIGS one but it's an old SCSI ROM version and reading around would suggest success is far from guaranteed with a ROM3 unit. Alternatively, someone suggested a
CFFA 3000 which seems to be a modern solution, a little like
the PetDisk. Looks good though but expensive. Has anyone had experience with this device?
