Backplane option connectors and the maintenance LAMPS switch.
cp06 chapter 002 "VARIANTI E OPZIONI / CHANGE AND OPTION" (dwg 140 130 65 6). The machine is configured at FOUR backplane connector positions – E03, E04, F03, F04 – and by one switch on the maintenance panel. The position names decode in the cp08 card-layout scheme as <ROW><CARD>, so E04 is row E card 04, and cp08 pp11-12 independently confirm which signals land on each. See docs/hardware-options.md for the tables and for what to probe on a physical machine.

Is the CPU stopped?
ALTO is the hardware stop flip-flop (cpu fo.97/98): it gates RIA0, so while it is set the CPU is attributed no work cycles. The delay line keeps turning and the channels keep running – a halted GE-120 still drives its panel – so a front end that models the whole machine (the wasm console) should keep cycling and simply watch this; a batch front end that only cares about the program uses it to end the run.
There used to be a separate halted field alongside it. It was redundant and disagreed with ALTO in both directions: set at init while ALTO was clear, cleared by ge_clear() while ALTO was set, and – the actual bug – left clear by every operator stop (ACOV/ACON, PAPA, PATE), so the CLI run loop kept spinning against a frozen CPU.

Write a flat image into core at origin, priming the parity store.
NOT a load path – programs reach the machine on cards. Test scaffolding, and the model behind the maintenance panel's memory key-in. Returns 0 on success, -1 on range error.
