Actually, the card described in the post above yours (especially the
mention of two-square socketed chips) sounds more like the Apple II High-Speed
SCSI card. It requires an enhanced Apple //e and is capable of data transfers
of 511k per/second (1mb/sec if connected to an Apple IIgs) when attached to
any hardrive, CD-ROM, etc.
The Apple ProFile interface looks quite difference. It mostly has
ordinary-style IC chips (ie - 74Lxxxxx type) and one 24-pin ROM chip; all
are socketed btw. It does have a 25-pin D-style female connector hanging off
it, but your right, it's definately not a SCSI (or even SASI) controller.
My ProFile controller is marked "Apple II Interface 820-5006-B", though too
bad I never recieved any ProFile HD to try hooking it up to. Which brings
up another point -- Can this controller be used for connecting something
_other_ than a ProFile 5mb/10mb hardrive? If not, it's rather unless to me,
unless I happen to stumble across an ancient ProFile some years from now! :)
