Black Knight (1980) was my first pin. And no i no longer have it.
I bought it back in 1988 for $450. The dick head i was living with stuffed it up on me. one of the wires broke off the coin switch so he tried to put a credit up on it by touching the wire that broke off the coin switch on to one of the flipper wires. That totally killed the cpu board. then i left it with another mate to look after and he shifted house but left it behind.
don't know what ever happened to it.
