	The front panel connects to the CPU and MMS through port A, such that a flat ribbon-cable covering from Aa13 to Ac32 (inclusive) of the CPU and MMS mates up with pin 40 to 1 on the control panel board of the ND-100 display. Aa13-Aa32 goes to odd pin numbers 39-1, while Ac13-Ac32 goes to even pin numbers 40-2. Do note the reversal of the pin number order between the two connectors, which corresponds to the 40-pin connector being mounted the other way around rather than both with the lowest pin number on the same side.

	On the older solution with split CPU and MMS, the CPU handles the signals to the control panel section (Aa13-Ac23) while the MMS handles the signals to the (optional) display section of the front panel (Aa24-Ac32). On even older systems, a ~~connection~~ on the control panel exists for a connection to the power-supply, for a standby mode that was ~~discontinued~~ around 1980.		On the older solution with split CPU and MMS, the CPU handles the signals to the control panel section (Aa13-Ac23) while the MMS handles the signals to the (optional) display section of the front panel (Aa24-Ac32). For even older systems, a plug on the control panel exists for a connection to the power-supply for a standby mode that was made obsolete around 1980.
