			Some buttons isn't lit up and doesn't need lamps. Unlit lamps are "MASTER CLEAR", "SINGLE INSTR", "SET ADDRESS" and "DEPOSIT".

			A lot of the switches are bad and is needing replacement. NOS from eBay, 5 switches is ordered.

			The operators panel is connected to the '''110 Panel buffer''' which buffers the key presses and two '''140 Lamp register''' cards. The lamp register selects what to show at the bit indicators.
