APPENDIX C

VIC 20 COMPUTER

A VIC 20 computer model is available on THEC64. The VIC 20 is the predecessor to 
the C64. The C64 and the VIC 20 share the same keyboard on THEC64, and the same 
commands work on both computers for loading, saving and verifying programs on 
disk.

However, the VIC 20 differs in a number of other ways. The most obvious differences 
are in its video and audio capabilities and the amount of memory available. The C64 
only runs C64 programs, and the VIC 20 only runs VIC 20 programs.

In Classic mode, press 

, select Options then Device settings > Computer model, 

and choose a VIC 20 model (PAL or NTSC) as the current computer.

In Classic or Carousel mode, you can also choose to make the VIC 20 the default 
computer model when THEC64 boots to Classic mode. In Carousel mode, select the 
Options (spanner) icon on the HOME screen then select Computer model and choose 
VIC 20 (PAL or NTSC).
