I learned long ago the basic rule about how everything electronic is smoke powered, DON'T LET THE SOMKE OUT of electronics.
The chips run on magic smoke, if you let the smoke out, no more worky
Yepper, plenty of times I will just swap a chip with the key off. The emulation stuff can get a bit weird at times though. The clearing ram thing is mainly if things have gone fubar. If I can, I pull the + cable and hold it to the negative to drain everything quicker.
