Dead Perfect Billiards MC8123A donated itself to science.
Desoldered the aluminium cover and bottom little pcb and magically appeared a black NEC MC8123A.
Apply some more heat and the potting mix turns to rubber and can be chipped/peeled away to expose the little ceramic pcb holding the battery and a 3771 reset chip.
The bottom still has potting mix intact, so more heat and chipping away with a screwdriver reveals this.
Unfortunately the solder holding the legs on melted and they came off. All thats left is a ceramic pcb with what’s probably glob tops.
Unfortunately I don’t have the chemicals to dissolve this stuff and heat doesn’t seem to do anything to it.
I wonder why there are 6 solder points on the top of the pcb? Maybe a way to program the MC8123’s encryption ram?
