What had happened was, when I unsoldered the metal shield of the C64 to do some other work on the board, I had made a mistake in soldering a bridge accross (I think it was FB8) to the metal shield, which grounded it. No damage was done as far as I can tell, and all seems to works well now. Thanks for your help! Henry. PS. I converted this NTSC C64 to a PAL, and everything works good except I cannot get color. I have a 1084S monitor which can display both NTSC and PAL modes. Any idea as to why I cannot get color? - This message was sent through the cbm-hackers mailing list.
