(I apologize if I've missed an obvious place to find the answer to this.) Where's a good place to buy RAM for old Macs? It seems like the SDR 168-pin SDRAM in my Twentieth Anniversary Mac has notch positions that don't correspond to most of the RAM I can find for sale online.
Wikipedia says:
> The first notch is the DRAM key position, which represents RFU (reserved future use), registered, and unbuffered DIMM types (left, middle and right position, respectively). The second notch is the voltage key position, which represents 5.0 V, 3.3 V, and RFU DIMM types (order is the same as above).
If I'm reading it in the right direction, the TAM RAM is registered 5.0 V:
