Almost got myself in trouble by being nice...Tempest PCB swap
An arcade buddy of mine needed to borrow my Tempest to test his spare PCB set. I had just finished the final rebuild of the game only an hour earlier, with a full cap kit installed on my Tempest PCB set and a final cleaning of all monitor side mounted transistors.
Anyhow, I stupidly leave my monitor plugged in and we boot his PCB set only to find that both start buttons are solid and the spot killer is active. The bad part about it is that I noticed a burning electrical smell...very bad news for me! Thankfully the game was fine when I booted to my PCB set and it ran well for about 45 minutes before I had stop playing in the arcade. I think it might have been smoke coming off of the degausse circuit, but I'm not sure. Remember, always unplug the monitor when testing unknown PCBs, learn from my mistake!
All of this brings back bad memories of my old Centipede PCB that used to eat monitors for breakfast until I replaced it. Whew, too close!
