Identifying an NTSC or PAL VIC-20 JiffyDOS is available for the VIC-20, however, you must know if you have the NTSC VIC-20 or the PAL VIC-20. NTSC is the video standard used in North America while the PAL video standard is used in Europe, Australia, and other countries. Commodore made two different versions of the VIC-20 for different parts of the world. Obviously, if your VIC-20 was originally sold and used in the US, it will be the NTSC version. However, many VIC-20's have been known to move around the world a bit. It's easy to tell which one you have with a simple PEEK command from BASIC. Turn on your VIC-20 and enter the following command: PRINT PEEK(60900) The response will be 5 for the NTSC version and 12 for the PAL version.
