Corey Cohen came up with this easy method of creating a remote switch panel for the Brain Board. Here is an image of his prototype version. Knowing Corey, I’m sure that his final version will be mounted on a nice plexi panel.

One DPDT switch controls which bank on the brain board is selected. Corey has loaded integer basic and the original monitor onto his second bank. The other SPST switch controls whether brain board or motherboard roms are selected after reset – this second switch is essentially the same as the firmware board toggle switch.

One wire needs to be added to the back of brain board to connect Apples reset to the DIP socket at pin 2. Reset can be picked up from the onboard switch location. It is the center of the three holes.

A ribbon cable is used to connect the remote switch box to the Brain Board. As you long as you stay within reason, longer ribbon cables than pictured should pose no issues. The only active signal is reset, which, when asserted, is held low for relatively long periods of time.
