I've been earning some money doing Mac assistance and installations for a while, and I recently encountered a very weird G4 tower of a customer of mine. While installing a RAM card, I found myself wondering if this tower could be beta. There are a few things that I discovered about this G4 that doesn't register with what a "normal" G4 is like...: 1: It has a set of LEDs on the motherboard, namely near the CPU, internal ATA(?)/SCSI(?) bus, and one by the RAM slots. 2: The layout of the motherboard doesn't match the pictures in MacAddict. 3: It has a massive heat sink that looks like it was designed for a dual processing system, but only has one processor. 4: The feedback when loading into verbose mode on OS X (10.1, go fig!) names the tower as a "MacRISC64PE" or something to that degree - Not "Alchemy" or "Gossamer" or anything of that sort. 5: The logic board isn't green. Is there any "dead-certain" way of finding out if this is a beta Mac? The suspense is killing me!
