Nintendo Family Computer (Famicom) Teardown
Teardown
Teardowns provide a look inside a device and should not be used as disassembly instructions.
It's day four of our week of game console teardowns. We stole borrowed a hot tub time machine, went directly to 1983, and acquired a Japanese national treasure: the Famicom!
We partnered with Wired for this teardown to bring you a glimpse of one of the most popular game consoles ever. Check out their story!
For those of you born in this century, the Famicom -- short for Family Computer -- is the name of the Nintendo Entertainment System (NES) in Japan. Join us as we delve into the system that revolutionized the gaming world as we know it.

Step 3
¶
-
Fully assembled Nintendo Famicom console.
-
The Famicom was the first console to popularize D-pad controllers to acquire user input. Departing from the era of joysticks, the inclusion of the D-pad allowed for quick and accurate controls.
-
The controllers are similar, but not the same...
-
The first controller boasts the traditional layout: D-pad on the left, "select" and "start" buttons in the center, and "b" and "a" buttons on the right.
-
However, the second controller has a built-in microphone and a volume switch at the expense of the central "select" and "start" buttons... Cool!
-
This is the only console we know of that has a microphone on one of its standard controllers.
-

Step 6
¶
-
Two antiquated connectors exchange signals between the controllers and the board.
-
Want to disconnect a controller? Gotta remove the bottom cover -- but that's pretty much it.
-
-
Controller II has an extra wire for microphone input and controlling the volume.
-
After disconnecting them from the board, the controller cables can be lifted out of the case.

Notable chips on the board include:
-
Ricoh RP2A03G 8-bit, 1.79 MHz CPU
-
Ricoh RP2C02G-0 8-bit, 5.32 MHz PPU
-
Toshiba TC40H368P hex bus buffers
-

-
Hitachi HD74LS139P decoder/demultiplexer
-
Fujitsu MB74LS373

Unsurprisingly, lead solder abounds on the bottom of the board. RoHS standards weren't established until 20 years after this puppy was made.
