Interesting point = KISS pinball filled the coin box more than any game of that era. I recall "service calls" due to the fact the the coin box was full and blocking the coin chute
You'd remember better than me - they were old hat by the time I am talking about.
Talking machines were the go when I got into it - Gorgar, EBD, FP, Xenon.
The only reason that we looked at Playboy was for the ahem, artwork...
I remember playing the first game on a brand spankers Firepower 2 - so 83-84. (makes me 13-14 - sounds about right)
Just checked IPDB for the dates (to make sure I am not senile yet) - they made 3400 FP2's! Where the hell are they all? And why don't I see many (any?) for sale?
Knowing what your "good" KISS will turn out like - I'm tipping it won't get many games...
Also tipping you have the NOS bits tucked away somewhere waiting for the day too. (Good on you!)
