Konami Pre-Jamma

Adapter which supports all the pre jamma Konami games with support up to 3 buttons (Iron Horse).
It has the possibility to choose alternate button controls for Hyper Olympic/Hyper Sports as in the original cabinet.

Supports additional right speaker for Gyruss pcb stereo music
NOTE: it can be used to test also TECHNOS pre jamma games like Mysterious Stones/Scrambled Eggs/Dog Fight/Exciting Hour but the controls will not work since
they are wired differently.
A customized Jamma adapter will be designed soon
