Colecovision and flashback controller difference

[pimpmaul69]

I thought i saw a discussion on this but doing a search brings up nothing. As far as pinouts and circuits what are the differences. I wanted to make a splitter for a colecovision flashback controller and an atari joystick. I thought i had seen somewhere that the flashback coleco had a chip in the controller. Any help is appreciated. And i apologize as im sure there is another topic on it.

Here are some pics of mine from my experiments (there is no chip in the flashback controller ). I was able to breadboard a controller to work. Keep in mind that the directional inputs need 1k resistance on each input.

 

Looking at the original coleco controller, you see tons of diodes and only 7 of the 9 ports being used in the plug. the flashback uses all 9 ports in the plug. the original coleco controller encoded the keyboard inputs in the controller then passed them out on the 7 pins to the coleco. The Flashback uses 9 pins to encoded the keyboard which is one of the major reasons the flashback controllers are not backwards compatible nor can a original controller plugged into the flashback.

 

I have considered on making a controller for my flashback, but dont really see the point. rather make one for my original colecovision and/or put a usb out on it for any emulator I want to use on the PC for the colecovision and such

Thank you.

Is the pinout different on the adam controller?

@thevnaguy I was looking to make an adapter cable for the fb controllers like i did for my fb intellivision controller.  i didn't do any 1k resistance for those.  is this unique to the colecovision?   you're having a 1k resistor for each of the 9 pins?

Yes it's not 1:1   Supposedly it was suppose to be made to be compatible but wires got cross (ha!) and it turned out to not be the case.

Ah i see 1k resistance for joystick only.. yikes yea they really did a number on making sure coleco fb isn't going to place nice with original system..  at least the intellivision was just re-arranging the wires..  bummer.  I was hoping it could be done easier.  thanks @thevnaguy for sharing your experiment!
