- Most generic clones use 9 bit SIMMs. You just need 2 at a time for
- 386SX machines and 4 at a time for 386DX and 486 machines.

-
- Most Macs (Plus, SE, SE30, II, IIx, IIcx, IIci, IIsi) use 8 bit SIMMs,
- 4 at a time. Don't know about Quadras.
-
-
- I think the Wide SIMMs are more often seen in the workstation world.
