THIS IS FOR A PCB ONLY. FINISHED BOARD IS FOR REFERENCE PURPOSES
DO NOT MODIFY THIS BOARD AS SUGGESTED IN THE DOCUMENTATION!!!!!
THAT IS FOR AN OLDER VERSION OF THE GERBER FILES, AND IS NOT REQUIRED ON THIS VERSION OF THE PCB. THE BOARD IS CORRECT.
This is a PCB designed to construct an ELM GAL Programmer (see here) suitable for programming of GAL16V8, GAL20V8, and GAL22V10 PLDs. This is the same board as seen on the Retrobrew Computers project page.
You will need a DOS based computer with a parallel port in order to use this programmer. Here is the necessary files which include the PGAL software, and information about building the board (including a Bill of Materials).
