Troubles with 7200/8200

[highlandcattle]

Hi I got two powermacs 7200 and 8200 (same as 7200 but different casing). And both have been stripped of their ram and video ram. When i start them up, nothing comes on screen. I have some ram from a powermac 4400. and a quick google search shows their both 168 Dimms but I can't get the ram to fit. And I don't want to force it. Can I assume that the ram types are somehow different? Can I start up these macs without vram?

I had the same problem with my TAM, which takes 5V chips. The only ones I had were 3.3V, and the notches don't line up. You'll need to keep an eye out for these, or order them in.

The 7200 used the same VRAM modules as the 7500, 8500 and many of the Power Computing Clones. They were 1 MB capacity.

I have a bunch of them around somewhere, but I'm not sure I can lay my hands on them (remember where they are) easily. I also remember that the ones that I have work in Apple machines but don't work in Power Computing machines, or maybe the other way around. I haven't thought about them in years. I picked up a lot of 1500 of them at the auction when Power Computing closed down. Sold most of them back then, but have thirty or fifty still laying around somewhere.

the 5V vs. 3.3V thing is the problem here as well. the 4400 was one of the few macs that used 3.3V DIMMs I think so they wont fit in the 7200 which uses 5V DIMMs.

The VRAM problem can be solved by using a PCI graphics card. The onboard video is a pain anyways - like the rest of the machine.
