CPU Modules
1. Each CPU/Memory+ board has two sets of CPU connectors, marked "PROC 0"
and "PROC 1".
2. Do not mix CPU speeds.
3. Requirement — To run 250 MHz CPU modules:
a. Use only clock+ board part number 501-4286.
b. Do not mix 250 MHz CPU modules with CPU modules of a different speed.
4. The order in which CPU slots are filled is not critical. However, to optimize heat
dissipation in the system:

Fill all "PROC 0" locations on all CPU/Memory+ boards before filling any
"PROC 1" locations. To receive the maximum quantity of diagnostic
information, fill "PROC 0" on board 0.
After all "PROC 0" locations are filled, you can begin filling the "PROC 1"
locations, again starting from the lowest slot number to the highest.
