According to the documentation EK-M9312-TM-002 M9312 Bootstrap-Terminator Module Technical Manual there are two addresses to use for the Console Emulator.
165020 (765020) for Console with Diagnostics SW 1 and 7 on 165144 (765144) for Console w/o Diagnostics SW 1,5,6,9 on The switch settings below correspond to xxx004.. which is probably the first drive for the ROM in position 1 and does not invoke diagnostics.
