Hi! Check out a post about VC20 from my collection, on my retro computing blog. Some cool photos and videos there. Please leave some feedback if you like it.

PSU done by my friend, enjoy the video report

I had some time for more tests, so I ran some scene demos, blind writing load"*",8,1 nad run. The demos worked, the sound was entirely ok, bo I had all sorts of moving garbarge on screen. So is it VIC or Char-rom down?

Just one last question. How much amps do I need ? In one post I read, that 250 mA is enough, others say it should be up to 3 A...

Ok I admit I'm lame in electronics could you please throw me some links, so I know what to buy ? I thought that AC means Amplifying Current...

Will something like that be ok :

9V 3000mA
Input 100...230V AC 50...60Hz 6VA
Output +9V 3000mA DC

Ok, so will a 9V 4A 36W laptop impulse PSU be OK ?

Hi, I just bought myself an older VIC, with a 2 prong power input.
I have some spare c 64 PSU's , question is can I modify it to use it with my VIC ? I mean just connect 9V and ground. Is anyone using such modification ?

I will certainly leave the soldering to a professional

The AV cable is OK, works with two C64's.

So, no tutorials for Vic-20 NTSC->Pal conversions are available ?

I thought so, I just checked out some scene demos on winVICE using PAL and NTSC settings... I definitely want it in PAL

So is there a list of parts I should replace to convert it ?

Also, based on the screenshot above, do you think that this is a Char-rom, or VIC issue ?

cheers

Ok, so if it's not worth to convert to PAL , and if I leave it in NTSC, will I have problems runing pal games, and scene demos ?

Oscillator is 14,31818 Ndk so it's NTSC... is it possible to convert it to pal by changing the VIC and oscillator to 17,734472 ?

Ok, I found out myself, that it's usually a VIC chip issue: UB7 6560-101 VIC VIDEO/AUDIO White or blank screen, garbled or no video, screen full of (or few random) "garbage" characters. "Blind" disk commands may still work. Partial failure: Dark or smeary image, loss of color, ga...

Hi! I just got myself a nice Vic-20 of an auction site. The mainboard looks flawless, but after powering up I get a grey screen, on which I can clearly see the frame and border, and some vertical lines instead of letters, and even some sign of cursor blinking. When I press the keys I can see somethi...
