Hi, As far as the VIC1 and Kernal are concerned, I am sure they are not the issue because I have removed and tested them on a working VIC20. I have used the VIC1 and Kernal from the working VIC20 on the broken VC20, (as well as a working fully working Multi Kernal). The VIC1 from the working VIC20 i...

Thanks everyone for your replies! Yes, of course, I have a working VIC 20, which I have used as a reference. On the malfunctiong VC 20 I have substituted ALL socketed chips (VIC1 and Kernal) with 100% working ones. In particular I am sure that both the VIC1 and the Kernal are OK! Maybe the sockets o...

Hi Yes, I have the common Vic 20 (actually a German VC 20) with the common PSU. I do have a second Vic 20 whose Vic and Kernal have been used to try to fix and test the malfunctioning VC 20. All other chips are socketed included the CPU :-( Substituting the Vic and Kernal did not fix the white scree...

The missing 9v on the userport could be the problem because I am using a userport-powered SD2IEC, which might not be probably powered because of the dangling cable. I do not have an soldering iron at hand. Before I try to fix the danglin...

Hi I have an almost perfectly working PAL Vic 20 with a "Device not found error" and a possible culprit. The innocent chips (all tested on other Vic 20's) are: - both CIA - 6502 - kernal The most probably culprit is the "bridge cable" that is supposed to go from JP1 (near the use...
