The other is from Apple but I don't know what it
is. It has a cable
off the back to a 25 pin connector. On the board is "Apple
Computer 820-0153-A" Over one set of chips it says something
about "sandwich II". I don't know any of the chips on it (never was
great at IDing more than a handful of chips). Could post pics if it
would help.
This is an Apple High-Speed SCSI card. Allows you to hook up an external
SCSI-1 device to the IIgs. A bit finicky (termination power, and some other
gotchas), but works mighty nice when you get it all set up right. I believe
it will also work on the IIe as well. See Rubywand's faqs
(
http://home.swbell.net/rubywand/A2FAQs2CONTENT.html in general, and
http://home.swbell.net/rubywand/Csa2HDNSCSI.html for SCSI specifically) for
more details...
If you have no need of it, I can certainly use it in my IIgs...
