I've been asked a few times if i do work on old poker machines.. I've done a couple of old one arm bandits the last couple of years.. but i dont advertise it since i've been told that i stand to get into a lot of strife if i restore one to accept and pay out coins and the wrong people find out about it!! Now i don't know just how true this is but its something i always keep in mind anytime i'm asked to repair one
I won't touch the electronic variety (with CRT screens etc) but i'll usually look at the old mechanical ones.
I have one here to do at the moment for an AP member
