50 description = "Portable version of Commodore's version of Microsoft BASIC 6502 as found on the Commodore 64";
52 "Commodore BASIC" (cbmbasic) is a 100% compatible version of Commodore's
53 version of Microsoft BASIC 6502 as found on the Commodore 64. You can use
54 it in interactive mode or pass a BASIC file as a command line parameter.
56 This source does not emulate 6502 code; all code is completely native. On
57 a 1 GHz CPU you get about 1000x speed compared to a 1 MHz 6502.
