On mine, the motherboard uses a IM6312 for the
"microinterpreter" (dated mid 1977). And I assume that
the three IM6561s are ram chips (dated early 1978).
The rest consists of:
1 - IM6100
2 - CD4511
1 - CD4042
1 - F4075
2 - 74C74
1 - F40175
1 - CD4025
2 - F40098
1 - 74C42
1 - CD4069
1 - CD4011
1 - F4001
1 - 1K Beckman DIP Resistor pak
1 - 10K Beckman DIP Resistor pak
8 - FND 367 7 segment red LED displays
1 - 2.4576 MHz crystal
1 - 12 key keypad
4 - 2N2222 transistors
3 - 44 pin circuit edge connectors
1 - battery holder to hold 4 D cell batteries in series
and a few resistors, diodes, capactors and a switch
Now the "6951c-M1KX12" plug-in battery-backuped ram board
has 12 IM6518s.

Somewhere here I have the users manual and I am almost
certain that there is a listing of the microinterpreter
in the manual.
