INTV 2<-> INTV FB adapters. DIY?

[tripletopper]

I bought directly from Nurmix FB control to INTV 1 long cord adapters.

 

I heard the FB has all the circuits right but confused pin numbering conventions somewhere, therefore making a mirror image pin map.

 

If that's true, then INTV 2 and INTV FB adapters can be made with this middle adapter:

 

A1  F5

A2  F5

A3  F3

A4. F2

A5. F1

A6. F9

A7. F8

A8. F7

A9. F6

 

And since At Games has consistently made this mistake, then this would be a universal x original to x flashback adapter

 

Also wouldn't be bidirectional going both to FB consoles and from FB controllers?

I don't think At Games just reversed the pins.  It seemed to me that there was no rhyme or reason to the pin selection they went with.  The internal matrix on the controllers are the same, but then they're just wired to a completely different pinout.

Below is the pin mapping to adapt a flashback  controller to an intellivision ii or sears intellivision.  The same mapping in reverse won't work to adapt an intellivision controller to the flashback emulator.

I don't think that the above pinout is correct.  F5 is listed twice.
