. | Power Macintosh 7100OverviewThe 7100/66 was the middle of the Power Mac line when
Apple introduced it in March 1994. Built into the Quadra 650
case, the 7100 contains three NuBus slots and a PDS. To save
money, the 7100 uses RAM for video (up to 615 KB, depending
on resolution and bit-depth) and a separate PDS card with
VRAM, making it very easy to work with two monitors. For
best performance, use the video card, not motherboard
video. The 7100 was upgraded to 80 MHz in January 1995. Variants7100av. Includes video-in and video-out. Supports
19" and 21" monitors. Has 2 MB VRAM. (AV card can be added
to any 6100 with a free PDS slot.) Details- 7100/66 introduced March 14, 1994; discontinued

- Because the 7100 uses up to 640 KB of system memory
for video (unless you're using an AV card or NuBus video
card), you can really boost video and system performance
with a 1B L2 cache, according to The
L2 Company.

Caution- Beware bogus 256K cache module AP2544-02 -- it
doesn't do anything on the 6100 or 7100. Full details on
The
L2 Company website.
- Never run a 7100, 8100, 8150, 9100, or 9150 without a
PDS video card or a PDS terminator. This can damage the
motherboard. If the video card goes bad, you can replace
it with another video card or use motherboard video after
installing a PDS accelerator or "Apple Terminator, PDS,
WGS 81XX." Apple
