The AST cards were part of Apple's bid for corporate acceptance, along with Tokenring networking and parity RAM. Phoenix Technologies as well as Apple had a hand in the card's design according to contemporary reports. Sadly I don't have much technical data on the cards. Can anyone tell me whether they used an 8088 or 8086 processor? How was RAM provided?

There were actually two cards- a Mac86 which was an SE expansion board and the Mac286 which was Nubus. I've never seen a Mac86 in the wild, but the Mac286 was basically a single (er, two) board computer which interfaced to the Mac and had its own memory. 1MB was the normal memory on a Mac286, though the later version could max at 4MB.
