I recently acquired a Famicom and took a few pictures of the controller insides while cleaning them.
Controller I
Controller II
The chip on the left did not photograph well, but says: Toshiba TC4069UBP / JAPAN 8546HB
Something really weird about my Controller II, is it doesn't seem to have a microphone in it at all! There is a cavity behind the mic hole where it looks like one belongs, and there are two holes in the PCB with solder over them where it looks like a mic might attach. Has anyone else ever seen this? Does anyone know of a good replacement part I could stick in there? (Also, there is a suspicious looking solder bridge on the IC, you can see on the top right of the board under the numeral 2. Wondering if I should clean that up... Edit: no, it's fine. That's bridging 5V supply to the SELECT and START pins. Exactly what it needs.)
