"Dumping" Protected GALs - Any Tricks?

[SuperSVGA]

If you feel like sharing the schematic once it's complete I wouldn't mind staring at it for a few minutes and making a wild guess what the registered one might do.

Yep, I'll upload it once I stop being stupid and getting turned around halfway though.

Here's what the current progress on the board itself looks like:

Along with the original scan:

There's a lot more going on in the inner layers than I anticipated, so it's going to take a bit to get it fully complete, but I should be able to at least get all the GAL connections mapped out.

you might want to consider using one of those "bitbang it with an arduino" methods to at least get it

Do you have a link to one of these? All I've been able to find so far is one that uses a custom PCB/shield, though I guess I could breadboard it if I was confident in the wiring.
