Might be useful for someone's Spock.

is single-sided with three chips. These are either 1MB or 4MB capacity.
These vintage SIMMs where pulled from an IBM PS/2 Microchannel PC...". The
Spock uses two. 8550-021 has only two 30-pin SIMMs. I thought I remember the
Model 60 at four 30-pin SIMM slots (the only one that way, or are you saying
it might be from a Passplay Brad?), but can't recall a 4Mb base RAM
configuration.
The source sound suspicious. Never saw any *4Mb* three-chip SIMMs
either. With the addition of the fifth SIMM grouped in, I still say buyer
beware. For the three-chip *1Mb* conventional SIMMs it may be possible to
change them (no patches visible here), but will they be drop-in compatible?

Hating people because of their color is wrong. And it doesn't matter which color does the hating. It's just plain wrong.

Kingston made some, I have 4 pcs (70ns, parity) of them in the ALR Business
VEISA (Siemens rebadged) machine. The Kingston Upgrade Book (1996) lists 2-,
3-, 8- and 9-chip 4 MB 30-pin SIMMs.
They are rare and they were expensive, for the latter reason 4 sockets on
the ALR memory card still wait to be populated.

Oops. Only one of these. Chips on the other three are labeled
9=HY5310000J-70 9147A
Silver colored contacts.

They do exist, and I might still have my set of them. (I purchased them new,
in the late nineties to upgrade a Leading Edge box with a TI 486SLC onboard.
(Yes, it's another turbocharged 386SX.))
Trouble is, I sold them a few years later to a teacher who was still using
her IBM PS/1 486 daily. She later gave me the machine and memory, but both
may have vanished in the flood.

Thank you Internet, and JLA Forums!!
I was searching for information on the memory type for a ParTech 3000,
and solved it here; GT-3009 = 4MB SIMM. Thanks again!
(Apparently these early models used a lot of similar parts to IBMs,
including the 4694/4695 registers' Intel 486DX chips, and BIOS
batteries, fyi).
