I've just cleared out my shed and found a bunch of stuff I'll never use, so I thought I'd offer it on here:
I've got a set of pedals and a steering wheel from a Leyland machine (not sure what):

There is some rust in the mechanisms but should clean up OK.
Next, a control panel and marquee from a generic JAMMA cabinet. The joysticks are included, but there are no buttons. The marquee consists of two perspex sheets with a printed sheet in between.

A 10p coin mechanism:

Standard power supply:

A 4 inch translucent trackball from a Crystal Maze quiz machine (can be illuminated from behind) with an Optic-pac board from Ultimarc:

A JAMMA-pac (or J-pac) board with one end of the JAMMA loom:

I would be interested in offers for any of this stuff. I am also looking for an I-pac board which I would be prepared to swap for one of the other boards...
Thanks for reading!
Forgot to say - I'm in the UK
