I applied a logic probe to all the chips on the board while it was running. I discovered two interesting things:

(a) I see activity on all lines (except /OE, which was constantly asserted, which I think is normal);
(b) if you accidentally short two data lines together, the Amiga gets extremely unhappy and crashes. Who knew!

So I think this is pointing more and more to a bad chip. I have some sockets on order and once they arrive I'll try desoldering them. Once I have at least some socketed I can try swapping them around to see if the fault moves. That should make it trivial to identify which chip, if any, is bad.
