Oh yes...I forgot about that point. It would've been nice if
it had the VRAM upgrade of other PPC machines. The PowerCurve came
standard with 1meg VRAM and was upgradable to 4meg.

I have a NUBUS video board (Radius PrecisionColor 24x) but
have never used it because it won't work with the Sonnet CPU upgrade.
The Apple AV PDS card is supposed to but it's not faster than the
onboard video, just offers more output options.

Yes, 256k was the standard cache DIMM size. 1MB was the
maximum that could be used. The cache was optional on the 6100/60.
Not sure if it was optional or standard on the 6100/66.
