Hey guys. I managed to come across this commodore 64 from someone. The image below shows that when powered on, it gives a strange display. I've never worked on vintage computers / game systems before so I'm not really sure where to even start with this other than completely dissecting it and checking for bad solder joints which I didn't see.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Commodore 64 Display problem.
Lol well I plugged power into it and measured volarge at various legs on the board. I was getting 4.3 and 5.1 volts. Can't really get my multimeter leads in the power supply end given how narrow it is also without knowing which pins should be what. I've also found 8 Texas instrument chips labeled ap8410. I'm assuming those are the ram since there doesn't seem to be 8 other identical chips.

Re: Commodore 64 Display problem.
8410 is probably the date, year+week
so 4.3 souldnt be there.
