Problems with a VIC-20

Hello all, I'm dropping here a request of help from a new Italian member, who was writing in Italian here.
A rough translation of the problems encountered (some are not so clearly explained):

Ho fra le mani un Commodore Vic 20.
Collegandolo alla TV funziona correttamente.
Ho provato a collegare due datassette ma non riesco a gestire le cassette.
Ho provato ad utilizzare la princess di Manosoft, si avvia regolarmente ma con le cassette stesso problema.
Avviando da comando l'utilizzo della SD non succede nulla.
Non vorrei che le porte cassette e seriale non funzionino correttamente.
Ho anche una cartuccia, quella si avvia correttamente ma durante il gioco si blocca tutto.

Ho provato a smontare il Vic e pulirlo dalla polvere, ma il risultato รจ sempre lo stesso.

Spero che qualcuno possa aiutarmi....

Grazie,
Angelo
I have a working Vic. No screen problems connecting it to a TV set, but:
- Two different Datassettes are not working.
- Manosoft Princess works OK for PRG files, but no luck with TAP files.
- Also have one cartridge. Plugging it, it fires up, but hangs during the game.
- Tried to open up the Vic and clean it from dust, but no luck.
Can it be a problem on serial and/or datassette ports?
TIA
Angelo

Hi,

I would try checking the internal fuse, if it is blown the datasette won't work.
That would probably only be the problem on a newer Vic that uses a c64 type power supply though,
not the older ones like mine that has only 9-11v AC input.

If that isn't it try swapping the 6522's if possible, hopefully they are socketed on your board.
