Hmm, I've got one (a HP-41 simulator), around here somewhere.
If I remember correctly, it even outputs bar-code (TeX source),
so you can load the programs into your real HP.  You could even
use 'symbolic programming' (peek & poke on the 41).  Last time I
worked on it, I was attempting a window based tool for it.
(The ultimate test would be making the goose fly backwards, no?)
Perhaps I should look at putting it together and giving it
to Rich Salz?  Naw.. who would want to run HP-41 simulations 
on their Cray?		:-)
