Re: Help with WHITE screen issue
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...

Re: Help with WHITE screen issue
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...

Re: Help with WHITE screen issue
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...

Help with WHITE screen issue
I have just aquired a Commodore VC 20 (PAL for the German market). (No "I" in the name because it was meant for that German market and VIC would have sounded like an F-word). The first time I powered this poor VC 20, it, sort of, started with random characters but froze soon after. Now if ...

Re: "JP1 bridge cable"? What for? Device not found error
Hi
My SD2IEC refuses to be powered by a different computer than the one it is connected to through the serial cable.
I will have to first propoerly solder the JP1 9v power cable and see if that is enough.

Re: "JP1 bridge cable"? What for? Device not found error
Thanks a lot Mike for your help! You are right about the VIAs. 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...

"JP1 bridge cable"? What for? Device not found error
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...
