One of these days, I keep meaning to harvest the right
chips off of,
 say, a 16MB 72-pin SIMM and transfer them to the 4MB 30-pin SIMM to
 fully load it.  That would bring one of my boards up to 32MB, a decent
 amount for knocking around on, given that it's a 486-DX100.
 If anyone has ever seen an 8MB 30-pin SIMM, I could put about 16 of them 
to use.
    Hi all, greetings from Brazil, first message here ;o)
    Well, there is - believe it or not - 16MB 30-pin SIMM. I always thought
it was a mistake, but I saw that with my own eyes. Unbeliaveable as it can
be, there is only ONE equipment I saw using that, which is a Equinox (or
Ensoniq?) music keyboard. It was the first and last time. I hadn't ever
stopped to think how can it be possible (maybe a non-standard pinout) but it
is true indeed, 16 MB SIMMs, four of them making 64MB. Believe it or not.
