Someone I knew at work had a Whirlwind that needed a minor repair. I
went over and fixed it for him and since it was very easy I didn't charge
him anything. Later on, he asked me if I would be interested in buying it
for $450 and he would bring it to me. It was in great shape and there
was nothing wrong with it. At the time, I was strictly into EMs and
I almost turned it down. Then I realised that it was too good of a deal
pass up and bought it. Later I found out it was a prototype serial
#2, the second one made. It has production roms in the game but
it came with prototype roms revision 0 in the cash box.
