Speed BASIC 128

This 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.

There are some SYS commands that can be useful if you need to turn on 2 MHz all the time with blanked screen for a while (FAST isn't working properly with this running).

• SYS4864 - Install SpeedBASIC (called on RUN already)
• SYS4867 - Remove SpeedBASIC
• SYS4870 - Enable fast mode (2 MHz all the time)
• SYS4873 - Disable fast mode (2 MHz in border)

Two Variants

There are two variants of the program. One that can be loaded as a BASIC program to be started with RUN and one intended to be loaded with BLOAD and started with SYS4864.
