Introduction
I’ve archived copies of David’s original work that spawned a hundred imitations.
David’s work was seminal in that it created the opportunity for literally anybody to program the PIC16C84 (which was the first EEPROM based, and thus re-programmable, PIC.) It didn’t hurt that Microchip was giving away the assembler for free on their web site.
