Mega CD Repair


Recommended Posts



I am currently repairing a Sega Mega CD, but am having trouble locating a chip - BA6393FP. I can find plenty of 8-pin chips with the same designation, but can't find a supplier of the correct CD driver chip. Does anyone know a source for these?


Thank you

You should be able to drop in a BA6396, which is still available from shops on eBay. If pins 5 + 6 on the PCB aren't isolated from the rest, as grounding N/C pins is common, you'll have to lift or clip those leads on the BA6396, as they added external connections to the internal 5v regulator on this IC, and grounding those pins will short out the internal regulator.
