I got my childhood c64 out of storage found most of it minus serial cable and monitor cable. So I checked out the power supplies for the 1541-II and C64 both tested ok, under loaded conditions... I don't have a scope so can't tell how much ripple is on the line.
Plugged it in and no light come on, did some power checks and found the din connector had dry solder joints and the power switch was faulty, so re soldered the din connector and cleaned the switch contacts.
Try again, light come on and black screen. Bugger, check for hot chips, none seem hot, the VIC and SID are warm to the touch.
Now the strange part, if I connect the datasette and press any button (rew, fwd, play) then turn on C64 it works, I can even load games from tape and play them just fine, when stop is pressed (on datasette) the computer crashes immediately. I have also noted that the datasette dose stop and start as normal during loading and game play. It seems there must only be a minor fault with this machine I would like to fix it or find someone who can. Or should I battle it out on trademe? Any advice greatly appreciated, I have purchased another power supply and serial cable so will try that when it arrives. In the meantime I am going to make a video cable for my C1802,
