However, I recall that there may have been some constraints, but not that severe. Basically it takes from 1 to 8 SIMMs. If the SIMM uses 256Kbit chips, then 1 SIMM = 256Kbytes. If the SIMM uses 1Mbit chips, then 1 SIMM = 1Mbytes. You cannot mix 256K with 1M. I'm sure that the following configurations are supported: 4 x 256K = 1Mbytes 8 x 256K = 2Mbytes (this is how mine is configured; it seems the best size for current GS software) 4 x 1M = 4Mbytes 8 x 1M = 8Mbytes (may not properly support DMA requests)
