Speed BASIC 128 is a small tool that enables 2 MHz in the border when running standard BASIC programs in 40 column mode. If you are using the 80 column screen only you should just type FAST and don't use this program. Load and run this program before you run your BASIC program to get more speed when using the 40 column screen.
