Ok, I am sure it has been mentioned before, but clearing an S2000 creates more problems than it solves. You had a working machine, if you couldn't get the key menu to come up, it was probably because you had credits on the machine. Always ask before you do a clear. Now you have to setup the machine from scratch as the defaults are more casino friendly than home friendly. I have cleared my s2000 once in 6 years, just to go through the procedure, but I believe that inserting the clear involves doing some button presses in the front. Did you read the VFD display to see if instrucitons popped up? Since the clear is destructive, it requires user interaction for verification I believe.
