PIC 16C84 programmer for Centronics port

Among the most popular shareware programs for PIC16C84 programming is PIP02 from Silicon Studios. The circuit shown here also uses PIP02, but in combination with a special driver written by Dave Tait. This driver, DTAIT.EXE, allows PIP02 to communicate with PIC programmer hardware via the parallel printer (‘Centronics’) port. The hardware does not amount to much and is cheap, too — the PCB-mount Centronics connector is probably the most expensive part!
