38 people RSVP's, but only about 18 people actually came.  Surprisingly mostly computer engineers who work with embedded systems.  Plus a health specialist, a few students and some academic faculty.  There were about 1/3rd of the audience who were unfamiliar with the old 80's tech, the rest were all in the right age bracket to remember it.  

Its a fairly specific group, all people using Python in some form or another.  They just needed someone to do a talk...  And mine apparently was 'really interesting' though it didn't quite go the way I'd hoped (too many 'ummms'  

 )
