I still like the idea of using the LSI Logic family instead of the
IDT. For a project like this they have some advantages - mostly that
the DRAM and bus sizing stuff is on-board.
I can't find the info I used to have on this chip family. I seem to recall
that the bus sizing stuff is very limited; basically, it lets you use a
narrow (8-bit) boot device, and that's it. But I could be wrong.
Are the FPU and non-FPU versions pin compatible?

Why is PGA a virtue and PLCC "lousy?" My one experience trying to remove a
high pin count PGA from a socket was not good, whereas I've pulled PLCCs
without hassle. PGA is more expensive to manufacture, too.
