Useful little boxes.

You can use 4 meg or 16 meg sticks _in_pairs_ in any bank, or 32 meg sticks
_in_pairs_ in Bank 0.  Look carefully at the motherboard silkscreening,
since the various slots and banks are not arranged as you might expect.  As
far as I know, 1, 2 or 8 meg sticks won't work.

You want 70 ns or faster, FPM true-parity SIMMs.  Ordinary PC FPM
True-Parity SIMMS are 36-bit, and work fine.  I have a Classic and an LX
(same basic box) each with 4*16+2*32=128 megs of PC memory aboard.
