Heathkit H-100 Library and Programs in DeSmet C

If you think you've exhausted the capabilities of your old H-100, take a look at the graphics functions and graphics programs in the sections below. These run many times faster than ZBASIC and GWBASIC. Learning how to access video memory to set pixels in C and assembler made possible a whole new world of programs.

These were developed using DeSmet C Version 3.03. I think everything you need for them to compile is here, but if you discover missing functions or macro definitions, let me know and I will find or recreate them. DeSmet C is available free on the internet.
