You may have an easy time finding these for next to no cost at all if you find
some 3-chip 256K-byte 30-pin SIMMs. You can remove two chips of this type from
each of them.

The chips on the mainboard are probably different in
that they are a smaller
profile but here's what they have on them:
.. KOREA
... 326Y
... KM44C256J-6
..
There are 4 of them soldered to the board, and they give the S3 section 512K
RAM with 256 color capability. The soldered chips are 20 pin but each side
has two sets of 5 pins with a space between them unlike the bare sockets
that are a symmetrical 10 on each side and longer than the soldered on ones.
4 chips are supposed to brig it to 1mb and allow more color and (I hope)
higher resolution without a color loss). It's a 1993 486DX2-66 server so
that might give you an idea. I know it's not quite a classic (10 yr old) yet
but it's close enough and I know the people here know more than most in the
chip level stuff.
I have no idea what the symbol made up of dots is, I've been out of the
component level field too long and my "memory banks" are toast right now
after a couple beers (been landscaping in the hot sun all day and it's time
to relax)
