I've (much to my frustration) picked on an 8500 for the basis of a
project and I'm having strange problems with it. The case was a barebones
8200/120 PPC 601 model - no HD or cd or ram or pci but a strange cache
chip - '7200 only DOS ok' - says the sticker????
Stripped it completely and sprayed everything beige matt black
Anyway, I got hold of a 8500 nitro mobo c/w 128 megs mixed ram, 4
megs vram and 256 cache - guy even sent me the original 120 604 processor
- and rebuilt the whole thing with the Nitro board. Took out the ram and
put 1 x 128 meg edo 60ns chip in - put Matshita 24x cd in the top bay -
kept the floppy in the second bay - 4 gig 80 pin UW Barracuda in bay 3 -
4 gig UW Barracuda (terminated on the adapter) in bay four - getting
those drives plugged almost resulted in 'lump hammer computer rage' -
access to the bays is awful but I'm over it now....
Booting from the cd I installed 9.1 on each of the Barracudas - then
booted from the HD to discover that my display is split between multiscan
(2 meg vram) and tv (2 meg vram) and try as I may I cannot get rid of the
mirroring (pram,cuda,whodoo,voodoo,different proc even a G4/400). Left it
to sit for a while....
Bought an A/V panel from the honourable RA Cantrell last week - I
really wanted to do audio on it - sprayed the beige panel black and
fitted it no probs but back to the iffy setup again. Wiped and
reformatted the HD in bay 3 and tried to install 9.1 - no luck - 'the
installer does not recognise this machine' - tried the install in bits
and got various errors like 'cannot find parts' etc but I got a bootable
9.1 system on there eventually and started from it to find that ASP
describes it as a 7600 and the vram is still mirroring - the right hand
edge of the desktop is off screen (maybe out of the house) eventually got
it back by zapping the pram but only for one reboot.
So here's my questions - with the 8500 mobo and the original
processor why doesn't ASP see it as an 8500? Where does ASP get it's info
from and how can I alter it? There's a rom slot on the mobo - what fits
in there? Is this really an 8500 Nitro board? Guru says 'Apple service
sometimes replaces 8500 logic boards with Apple part 661-1754 - a
remanufactured 7500 board. Part 661-1153 is the real 8500 replacement'
and does not list an 8500 A/V model - why not?
