Sometime in the mid '80s, someone at the Tektronix Computer Research 
Labs(Kim Rochat, maybe?) built a lab instrument simulation tool in 
Tek Smalltalk-80.  I distinctly remember playing around with it at 
the time, but for the life of me I can't remember what it was called, 
or find any papers or documentation on it.  Does any remember it 
(just to prove I didn't dream the thing), or have a citation or URL 
for a paper?
