My II+ needs a new escape keyswitch, keycap and encoder IC, just in case 
anyone reading this ever happens to be parting out a US-spec system (I'm 
guessing that a Europlus or J-plus encoder is very slightly different. Was 
also led to believe that there are a couple of different keycap styles for 
US-spec systems).

The keycap's probably the critical thing - I think there may be other 
sources for the switches (at least there were until a few years ago), and I 
suppose that a PIC-based approach via a small plug-in carrier board would 
be an option for the encoder if needed, although it would be nice to keep 
the machine original if possible.
