I still have the Dos software for mine (PEP/SPASM), alternately I believe Jim Robertson is working on a TM4 adapter for the Parallax. I have one and have started to consider selling it (With PicStart Plus, Warp-3, Needham's EMP-10 and EMP-20, and ICSP capability, some things here are somewhat redundant ) Parallax or Tech Tools may have the Dos software still on their FTP site somewhere, alternately. Should be able to teach a non-engineer to run most any programmer, I'd think. (Find an eager High Schooler, I know I would've loved that job as a kid ) Mark Ernie Murphy wrote: > > Does anyone know the algorithims to control the orgional Paralax (parallel > port) Programmer?
