This connector is very minor quibble the major one is
it does not
have *vram*! The video memory is reserved in one area in main memory
(1MB). Remember, video scanning is constantly on the go therefore
stealing just too much of bandwidth on memory access during that.
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.
Try a video card in that 6100, performance will jump
up. When I
found out this info, I was deflated because that means I must spend
getting the 601 PDS to nubus adapter bracket and video card, cache
stick if that 6100 didn't have it when I swap out orignal board in my
610.
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.
FYI: 1MB cache stick do *exist* but very expensive
appox 80US each
on ebay. Works in 6100/7100/8100. Question: When those x100's was
sold new did these machines has 256K cache stick by default or
optional item? This is important question because I want to keep
sellers honest if I ever decide to buy one of those parts or a
x100 system
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.
