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...
Anyone have an idea what these are, and what they're for?

I know of three machines which use 64-pin SIMMs: GVP Amiga accelerators, Mac
IIfx and certain AST 486es. Possibly some Apple laser printers, too.

How about 31 Pin SIMMs?

64 pin = Mac IIfx and Personal Laserwriter
68 pin = Mac VRAM simm
for example...

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.

Then what is that socket slightly smaller and apart from the memory
sockets on the mainboard of my color turbo slab?

Does it also work in NeXT color slabs?

According to http://www.obsolyte.com/next/, it is a DSP chip, allowing the
DSP to be expanded.

As someone else already pointed it, it is indeed a socket for DSP RAM
expansion. NeXT sold a 56 KB upgrade SIMM for that slot, and at least
one third-party hardware manufacturer sold an upgrade SIMM in the >256KB
range. Very few people bought them, though, so they're incredibly
difficult to find. OTOH it does mean that very little software exists to
take advantage of the additional DSP RAM. I'm not sure I could name any
off the top of my head.
