The text has some obvious errors. As I find them, I'll list them
here. See the sidebar for information on the use of the LMC Skip
instructions, and the status lights that they test. (Negative results
after a SUBTRACT are also explained therein.)
- p.149
- The location counter must be incremented after the fetch and before
the instruction is executed. (It must not be incremented after
the instruction is executed!)
- p.158
- The program counter register holds the address of the next
instruction to be executed (not the current instruction).
