www.thechipmerchant.com used to have a web page with all this information
on it, it was extremely useful. But I havent been able to find that
page for about a year now.
They had the chips listed in tables by manufacturer and chip number, and
then listed the number of bits of ram in that chip, for example 1Mx4
If someone still has this information, please pass it along.

For years I have been squinting at the numbers on ram
chips trying to
devine the capacity of Simms dredged from boxes of scrap, and I do "ok",
but I was thinking somebody must have a nice complete crossreference of all
the chip numbers.
I do well enough in weeding out the worthless 256k SIMMs, but stumble often
enough with 1 MB vs 4 MB. What I could really use is a list of all the part
numbers for chips used to make the 4 MB simms (if its not a 4 MB, most
likely its a 1 MB and can just be tossed in a bin.). Any tips?
BTW I have sorted a few hundred simms, so I do know the "basics" of chip
ID. Some parts guide must have a good crossreference though.
