Enhanced 6502 BASIC By Lee Davison.


Enhanced BASIC is a BASIC interpreter for the 6502 and compatible microprocessors. It is constructed to be quick and powerful and easily ported to most 6502 systems. It requires few resources to run and includes instructions to facilitate easy low level handling of hardware devices. It also retains most of the powerful high level instructions from similar BASICs.

EhBASIC represents hundreds of hours work over nearly three years, lots of frustration, lots of joy and the occasional twinge from RSI induced tendonitis.

EhBASIC is free but not copyright free. For non commercial use there is only one restriction, any derivative work should include, in any binary image distributed, the string "Derived from EhBASIC" and in any distribution that includes human readable files a file that includes the above string in a human readable form e.g. not as a comment in an HTML file.
