CHEVY TECH on C64, Apple II, and IBM PC-compatible, 1985-1988

Chevy Tech is a series of computer programs distributed by Chevrolet for various platforms over (at least) model years 1985 through 1988. We look at various versions found for the Apple II, Commodore 64, and MS-DOS compatible PCs, and can't help but find a few bugs and quirks along the way.
