Another 'whats-it' question here. I have two
kinds of, what look like 72-pin
memory...
The first is only 64 pin, has 8 chips (AAA1M300J-08 NMBS 9122),
with an empty spot for a 9th chip. Printed on the back - "1X964P A (in a
circle) 9115". Apparently made by Microtech. My guess is it's 1MB non-parity
memory, but I don't know what uses 64 pin memory sticks. I have 4 of these
sticks.
The second is 68 pin, 2 chip memory. Printed on the back, they're
made in 1994, in the USA, by Cubig Inc. Model number (I think) of VM512K.
512KB memory sticks? Have 3 of them...
AST and Mac IIfx use different types of 64 pin simms, could be for either
or neither.
The 68 pin is early Macintosh Vram, around the Quadra era I think.
