Basically, 4M SIMMs can be used on some expansion cards, along with the 55SX
and 65SX motherboard, and the new L40SX laptop.  Note that your SIMMs are
probably 85ns.

The P75 and Models 90/95 will work with 85ns or 80ns SIMMs, but they will NOT
use them as fast as its normal 70ns memory.  It can detect slower memory and
use it, but you'll lose performance... and that's usually why someone gets a
P75 or 90/95.  (Also... the P75 and 90/95 must add memory in pairs.  Two
SIMMs of the same type must be added at the same time.)
