Getting at the memory in a Powermac 8200

Question

Trying to access the memory modules on my Powermac 8200 - what does one do?
It seems that a total dimantle is called for - just to add 128Mg more of DIMMS
Anyhelp or tips would be gratefully received - an instruction manual in .pdf might help
Helppppppp!!!

Your suspicion is correct. Although it is a minitower based on the Catalyst board that was otherwise used in desktop 7200s, the 8200 is like the 8100, 8500 and 9500 at least, and others that I wot not of, in that the logic board stands vertically on the right (as you look from the front). You must undo the four captive screws at the rear, crack the joint with the metal case, slide the case forward slightly and then lift it up and off.
While the Mac stands there in its smalls you must remove the daughter card and PCI cards; and SCSI, audio, power, floppy drive and whatever cables from the top edge of the logic board. Out with the front power switch, which has a retainer for the logic board, and then the screw holding the brace for the board. Now you can winkle the board clear of four notch-and-lug retainers by moving it forward a tad, and then swing it outwards and away from the chassis.
I know of no manual for the 8200, but that for the NuBus 8100 from here is close, even though the 8100 is based on the Cold Fusion board. I do suggest that you replace the backup battery while you have the board out.
