ENIO NES expansion

[UglyJoe]

The Japanese and US versions of Excitebike are identical, so I don't see why it wouldn't work (aside from issues with the ENIO).

Would be neat to see someone try hooking up a Famicom Data Recorder to a Famicom Keyboard to a NES through this device, and see if the save and load features on the NES version of Excitebike work.

"[...] programmed in for potential product developments" indeed - it only took 27 years! 

It was somewhere on the web - Famicom keyboard connected to the NES. Directly.

Well hopefully i can show a nice little video of this very thing very soon, once a package from 80's Freak arrives at my house

[P]

But PAL versions and Japanese versions isn't identical so that might be more interesting to check. I doubt they took the feature out though, and the Swedish manual also states that the Save and Load functions is in there for a possible future use.

I'd be happy to test PAL versions also if anyone wants to send me a copy

Wow - I feel pretty foolish right now.  You'll need to make one minor change to the ENIO EXP board to make this work.  When I was designing the board, I kept seeing "AUDIO" on the FC EXP pinout and thought it was for input.  After going through the documentation on the Famicom Data Recorder I realized that the AUDIO signal was actually used to output audio data through the keyboard to the FDR.

The fix is pretty simple.  Remove R2 and solder a wire from the J6 Audio In pin to the J5 Audio pin.  No need to cut traces or anything.  Sorry for the goof.

Time for version 1.3 then

I can imagine a version of this that fits flush with the bottom of the nes and has it all built in
