Lexicon 480L Audio Memory IC HOT!

Hi Guys,

I have a 480L that U112 (74s472 is running very hot. The audio also breaks up in the reverb... can I just replace the chip or do this need to be programmed?

It's a PROM, so if you replace it, you need to program it with whatever is in the original part.

Yeah, I see that...

Neat how they are written, too... burning out "little fuses"?
