i have an Intellivision I, the numeric pads work fine, but the directional pad doesn't always work correctly. all of the directions dont work all of the time(which directions work are random). i've tried cleaning the MPCB but it still doesnt work correctly. on to the question...
if i use a male 9 pin D plug and connected the pins to their corresponding places on the board (where the original controllers are attached) , and mounted it to the case, would i be able to use this as a regular controller port to plug in a working intv II controller? or possibly could i plug in a genesis or arari controller so i could use the d-pad or the joystick and still use the numeric pad on the intv controller? also if i made a custom intv controller would i be able to use this as a normal controller by plugging it into this port?
has anyone done anything like this? or does anyone know enough about it to help me? any help would be appreciated
