The Good Old Days
Well there was a "feature" on the Amiga in Frontier where if you had a passenger on your ship and tried to sell it for a smaller ship (some sort of shuttle was the smallest IIRC) then you would get the credit back for the difference between your ships value and the shuttle but, due to you having a passenger on board, you kept your original ship......as you could do the sale by pressing one key on the keyboard and holding it down would repeatedly try to process it (increasing your balance over, and over again in the process) some people taped a dice onto the key and went out for a few hours.....allegedly.....
