freeplay adapter
To use this you just unplug the 8 pin plug in your jukebox and plug the above between the exsisting cable and socket.
Flip the switch one way and it's freeplay the other and it's normal operation.

constructed adapter

It can be built like this or put into a box.


This adapter circuit should work for all  M100A, M100B, M100BL, M100C, HF100G, HF100W, HF100R, HF100J, and HF100JL.
Unlike a version that is being sold on ebay this circuit will not release a single button press.
In other works if one key (letter or number) is pressed and a second is not the latch solenoid will remain on and not release.

It works by supplying a ground to the selector leaf switches which latches the selector solenoid. As long as the letter / number combo is completed the buttons will release and credit light will go off.

When time permits I will enhance this by adding a time out ct to disable the above if selection is not completed in a set time.
Which could be adjusted.

If anyone has the time and adds the timeout feature let me know, I'll include it here.
