That sounds like a great idea! I should be able to at least identify the functions of the specific chips used on that card.

Additional documentation is flowing in behind the schematic courtesy of that little birdie who all of us DG collectors know and love, and it's putting me in a really fantastic mood this morning. I'm feeling so happy that I think I'll buy my dogs a cheeseburger at In-N-Out on the way home tonight to celebrate. Now I'm looking forward to working on this project some more this weekend, rather then dreading the tedium of reverse-engineering a design with black-box chips!
