Rare card for the Apple ][ family.
Vista A800 8″ drive controller card with version 3.0 and 3.1 Boot Chips. The 3.1 Boot Chip is still in it’s sealed package! I had a hard time figuring out what this card was, but I knew it was for the Apple II. These are probably as hard to find as the 8″ disk drives they were used to control. I don’t have any 8″ drives, so the card and chip are sold as-is, untested.
Driver is here for use with the PCPI Applicard or StarCard: http://www.math.purdue.edu/~wilker/misc/DEVEL/0008/VISTA-DI.ASM
