Original Apple, fully tested PDS slot video card for the Power Macintosh 8100. This was supplied in the non-AV version of the 8100. It is referred to as the 4MB card because that is its VRAM capacity when populated with 4 x 512K VRAM SIMMS. This card is supplied here unpopulated and therefore has 2MB VRAM. Although never supplied with the Power Macintosh 7100, this card is compatible with the 7100 models.
