Well most had on board mine is an EVT without on board ROM so what I want to do is find a simm from a 7300, 7500,7600, 8500, or 9500 so I can boot it. I hate to solder ROMs to an EVT board that had them simm basedfound anything in the 7500 motherboard online pictures?
it's weird because it's a very common Mac model
If you find the code, I can check if I have it
Might be worth looking in service manual pics if they haven’t. They often picture prototype boards, but may well be too low res to get the part number.I’ll try ive been looking through what documentation I’ve found in my Vol 5 service guide (in the wiki section here) it talks about the ROM simm but not the number annoyingly
Yeah I’m beginning to think maybe take a 6100 rom simm and flash new 7500 ROMs to it/replace the chips.
