I decided to put the RAM back in the original since its working now, just in case there is a mod we forgot about. It worked.

Looks like I

The chain is as before. Port 0 RAM, then Math, then 64K, pin 9 unconnected.

Now to the FORTH module. Things looking good.

So when you run the improved SHOWPORT or Paul's MEMBUF, does the 64k "module" show up as one port or two? I suppose you could also execute FREEPORT(.05) then MEM(.05) to make that determination.
