The c-64 has a cap, or is it a pot(?) near the video chip on some models. You might want to try tuning that, with the power on, to see if you can get a color signal from the machine. The 6569R3 _is_ a pal IC, and your c64 IS set up for pal, but I'm guessing your 1084 should be able to display PAL without problems. I could be wrong, since I dont own such a beast ;) (I use a computer with tv out and tv in to rescan pal) On Fri, 30 Mar 2001, [ISO-8859-1] Marko Mäkelä wrote: > Hello Adrian, > > I'm forwarding your question to the cbm-hackers mailing list.
