Sorry if you have seen this once before, but our news feed went down shortly after I posted. ----------------------------------------------------------------------- I am planning on replacing several stepper motor controllers with PC clone motherboards. Does anyone have any code to run a stepper motor from the parallel port? Or an 8255 port? How about circuits for motor drivers? These will be diskless systems running the code out of ROM, so C or ASM source is what I am looking for. On that subject, I have found several PD LOCATOR programs to turn .EXE files into ROM images, but they all assume the target code is located ending in the F000:0000 area, replacing the BIOS. I would like a LOCATOR that I can use with the BIOS and supports the 55 AA auto-start ROM sequence that is built into the BIOS.
