Thanks.
I have already been pointed to this archive and found the listing.
Solved the problem too: happened to be a subtly different way the 2e
switches "language card" memory range.

This time around I build it for a new platform - the Altium NanoBoard2.

I suspect you don't have one because very few people do - they just 
started shipping. The project will be open source, so I'll publish it
shortly.

For the most part it's portable Verilog, but the top level had to be
in schematic form for the Altium tools to work.

This is a unique platform: it has a plug-in with 6 Apple compatible 
slots. So for the first time (?) there will be an FPGApple with access 
to physical floppies in addition to memory card "disks".

You can see it here:
