I've found two 2MB x 9 30 pin SIMMs in my

have used these? Each SIMM has four 1M x 4 and two 1M x 1.
I have 4 of something like those from a Planar-brand wall-mount 486
LCD+PC combo. It has a squarish motherboard, one ISA slot (on the
edge), with pin headers for VGA daughter card, off-board I/O
bulkheads, IDE and floppy, etc. It is _not_ PC-104 (but there might
be an unpopulated PC-104 connector space on it, I can't recall for
certain). The same motherboard appears in an keyboard/NET-PC I have a
couple of. Four 30-pin SIMM sockets, and the two types of RAM I have
are a 2MB no parity (4 x 1Mx4 chips) and a 4MB no parity (2 x 4Mx4,
but the odd thing is that the SIMM is half populated - there's room to
make it an 8MB 30-pin SIMM).
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.
