Let me know how it goes. Worst case, maybe I'll take a look at it if you
want Rich. I also have some stock of the Z80, 5380, PLCC ROM, GALs, etc.
I've found that for some reason the 574s and a couple of the right-hand side
ICs along with the GALs blow out. I guess they are linked in such a way
that they take the brunt of hit.
Here's two I've done:

The first one I had to replace all but one of the ICs. What fun that was!
That card was in really sad shape. The second one really wasn't a repair.
I was just reading the ROM and GALs. Thanks to Macdog for that one!
