This halts the microprocessor. If it is inadvertently placed in the ON position, a multicoloured pattern appears on the screen on power up.' I've no idea what switch 7 does. The manual also advises: 'Toggle switches are also found at position 4A on the CPU board. These are for maintenance only and should not be touched.' Looking at the circuit diagram, we see that: Switch1: No connection Switch2: on: pin 21 of ROMS tied to A12 line. Off: pin 21 of ROMS isolated Switch3: on: 'A' input of '139 ROM decoder tied to A12 line. Off: 'A' input of '139 ROM decoder tied high. Switch4: on: pin 21 of ROMS tied to +5V Off: pin 21 isolated My guess is that they select 2716 or 2732 ROMS. 2716: switch 3,4 on, switch 2 off 2732: switch 3,4 off, switch 2 on
