I have made a breakout board for the car Marty substituting the unobtainium cable required to output to TV.

V1 board tested successfully with mono audio, left and right audio, composite and s-video all working.

V2 board has been sent for validation to my tester. Once it is validated I will have a few available. It will be $75 before shipping.

Later I will try to make adaptor to use 3-mode floppy drive with it also.

This was V1 board. It worked fine but didn't have a method to secure in to marty.

V2 has smaller PCB and a hole above the pins. You use the original screw included on the car marty. Remove that screw and use it to secure this board to the car marty.

This is V2 board. Sorry for double post.

It will have LED on top of each connector, white and red for left/right audio, yellow for composite, orange for mono audio and blue for s-video. When it's validated and works I'll post here again. I'm hoping it won't need another adjustment.

Good call about the screw to secure the board.
I'll definitely take one.

Are you taking suggestions ? :D
I'm no too crazy about the red color, would blue or simply green be an option ?
Or even better, black, but that would drive production costs up I guess.

I already have a few red board.
Different color PCB is not expensive. It's just what I have now. Unless you want to pay $21 extra for black PCB.
Later my friend will sell these and he might have another color. I don't have time to run eBay store or business so I would like to just sell a couple to raise money for undumped games or games requiring redump. I am too busy developing new power supplies for towns and trying to unlock floppy titles. So I'll have maybe 7 or 8 of them available once my friend validates it. Once they're gone he can sell them so other people that might miss out can grab it.
I should note I made this board without owning a car marty. Everything was based on photos of the circuit board of car marty and it worked.

Ah ah, got it, red will do.
I'll have one when design is validated.

Keep up the good work.

My tester let me borrow his car Marty since I messed up screw hole alignment. Reordering black pcb I'll let you know when it's available

Car Marty breakout board is available. It doesn't have LED but has resistor ladder circuit and LED spots. The back is taped so it won't scratch car Marty. It will also come with a longer screw so it fits.

Here is a video of the board working. Left and right audio, composite, mono audio and s-video all tested working

Are there any of these boards still available? Been trawling yahoo for months for the official cable but of course, no luck.
