Ok so if you used a MEGAdrive, check continuity from those ICs to the points you soldered on the MEGAdrive.Are you saying I check continuity from disc drive pins to alternative pins on those small chips?
Am I supposed to be checking continuity with the thing on top of the mobo as well?I'm not sure what that is, but if it has something to do with the installation process I used a megadrive as opposed to directly wiring it.
