Yep I'd love a Black Knight 2000.. but you have to find one first! .... and they go for quite a lot of $$$. Ive only seen it on youtube but would love to play one.
I thought the Micro switches may have been part of the Electronic Flippers ... obviously not... thanks for that insight beaky.
My System 11a doesn't have these... it must use the 2nd contact on the main switch?
Yes those boards are interesting.... great to know where they came from.
