Ah the good old days of playing pins down at the Student Union Bar in between lectures and tutes - the bar manager conveniently had a spare key to the machine which the operator had left him to fix ball hangups.

It was a fair trade off to spend a few bucks at the front bar and get a dozen free games clocked up on the game in return.

IJ, Tommy Pinball Wizard and a near mint TAF were the machine I remember.

IJ particularly because I later bought it off the operator once I had saved up the funds to afford it  - the princely sum of $800.  

A hefty amount on at that time a student's part time wages.
