LM3000 Memory

From BenningtonWiki

The program memory consists of two 8-bit RAM chips.

One is the Instruction RAM, which stores the codes for which part of the microprocessor are activated at which time. This involves all the MOV commands, as well as the ADD, SUB, and BRA commands.

The other is the Operand RAM, which stores any values the program needs to provide. This can provide values for the registers to hold, values to be added/substracted in the ALU, or addresses for the branches to lead to.
