Let me know when you're sitting around bored, and looking for a 
challenge.  :-)  All this talk is starting to revive my interest in the 
MM/1.  I may have to get it running again soon.

I don't think most of them were _that_ much bigger, really.  I'll check 
my data sheets again and see what the UARTs were supposed to be capable of.
