Technical Notes
A. With the exception of the 2123-???, all PS/1's can accept double-sided SIMMs.

B. 4MB, 72-pin, 32-bit SIMM resistor pinout:
Pin 72 = connected
Pin 71 = not connected
Pin 70 = connected
Pin 69 = connected and resistored
Pin 68 = connected and resistored
Pin 67 = connected and resistored

C. The systems that utilize the Type 6 32-bit SIMMs are designed to accept Type 4 36-bit SIMMs as an alternative. In practice, PS/1 support has had poor results with 36-bit SIMMs largerthan 4 MB in these units.
