Another C64.. Will it ever end! ;D This one came to me as a dead black screen jobbie. PLA?
Machine in quite good nick. With a bit of a clean, it would look new.

Well, ok so no picture. Left it on for a bit, and one of the memory banks wasn't getting as warm as the other... Checked the signal on the logic, and it pointed to this. It no worky.

Nope, it's not a JiffyDos upgrade, just a copy of the original kernel on a 28 pin converter.

SD2IEC made from recycled C64 plastic. Against the C64 even though it needs a clean, you can see the colour match is spot on!

Innards! Oh look, a reset button! And a real nice old ceramic VIC-II chip.

Life!.. But only with the test cart plugged in.. If ya C64 is dead, but fires up a cartridge, you need a new kernel.

Done. All tests passed. Happy days and it wasn't the PLA. Heat sinks added, including 3 on the VIC-II as it's lost it's top hat.
