Port of DITHERPAINT99 (for the TI99/4A with EXTENDED BASIC) that has been optimized for the Sinclair ZX81/Timex 1000 computers. Changes make use of the unique limitations and features that are part of the ZX81. Developed using a modern text editor, tested on the EightyOne emulator, compiled using MCODER and tested on real hardware.
