Happ Optical Rotaries and KE72T

[antony30bc]

Anyone been able to hook two Optical Rotaries to the KE72T trackball interface?

 If you remove the default wire attachments from the rotary PCB's the KE72T trackball cable will attach to both PCBs. I am not sure if the wire pinout is the same though as I am not able to get it working. Windows is not even seeing the KE72 as a mouse, although I have the cable connecting the PS/2 mouse port to the KE72 mouse port.

Well I gave up on getting this to work in KE72. Just ordered an optipac.
Currently I have a direct to USB/PS2 trackball from Happs for the trackball. My Player 1 and 2 sticks are Optical Rotaries I had hoped to hook to the KE72T but that doesnt seem to work.

Since the trackball and Rotary functions wont be used at the same time, could I get by just using standard mame. XP lets me have multiple USB mice they just control the same cursor. With Axis splitting enabled for rotary games, and one rotary stick on Y axis, one on X axis I would think standard mame would work.

Let me know.

Some pics of current progress.
