2 hours ago, I just installed the following chips:
2x CIA 6426
2x SID 8580R5 + 6581
VIC II 6569R5
Chips with notch facing rear, used a power supply 12v DC center positive. When turned on I got the message that VIC II detection failed. Is VIC II 6569R5 compatible? I took it from my old c64 and it was working just fine...
Now I cameback to continue my testings and the board doesn't even turn on... Checked the power supply and even changed and nothing happen...
Could you please advise?
