The geometry engine board contains 4 SiliconGraphics GE12 geometry processors

PowerChannel2 bus interface ASICs, FIFOs, and glue logic

geometry performance of 10M polys/sec - on par with the much newer Nvidia GeForce 256!

Empty solder pads. A GE with 8 processors was never created. Warm up the wave soldering oven, I smell an upgrade.

The graphics boards require 3.3 volts, and their power converters are on the opposite side of the backplane, on their own daughterboards.
