Here is a cool video upgrade for vintage Macintosh computers. SuperMac introduced this card in 1991 to provide NTSC video input and capture on Nubus Macs. The card fits Nubus slots in Mac II series computers (Macintosh II, IIx, IIfx, IIci, IIcx, IIvx, etc.) and possibly others. It has a standard composite video input. Under software control the card can capture standard motion analog video for manipulation in the Mac or for viewing on the Mac's display.This particular card is marked "Version 1.0" . It comes with a floppy diskette containing SuperMac software.I tested this card and it’s in working condition!
