PowerMac 7500 (?) Guts
Well, going through a pile of stuff from the recycler, I found what I think is a 7500 motherboard. It matches the pictures I've seen on the internet of it (it also says TNT on the board). I also found the processor card (PPC 604e) a week earlier, as matching floppy and hard drives for it. It has no RAM, ROM, Cache, or VRAM. An interesting find, considering I found the pieces on separate occasions. Hopefully the ROM/RAM/VRAM/Cache will be found next.
The 7500 shipped with a 601-100 and no cache in the slot, if you found a 604E then it is from another machine (but will still work, 604EV will not). ROM is built in and cannot be changed. For VRAM you need 2 sticks or 4 sticks (must be in pairs, each stick is 1MB), RAM I think is 8MB minimum per stick, 8 slots to fill 1 at a time, or in matched pairs for a little speed boost.
