ive modified mine to use memory from a 8mb simm.(i can post pictures if you/anyone wants)
if your wondering how much this cost me to do,a 8mb simm is very cheap i only needed dil sockets for the conversion.
here is a small list of part numbers for reference:
TC514400
HM514400
Upd424400
MSM514400
TC514402
MSM514402
and a link on ebay.(bare in mind to fully fill that board to 8mb you need 16 of these and the sale is for one part)

be careful though,these part numbers also are available in different packages.so only go for the 20 pin dip package at around 80ns or faster.

Is there some soldering to do to use a 8mb simm?
