Chris Macie has sent messages to this list before... so perhaps he can find
himself and cajole himself into digging out his Apple II Smalltalk?

But VisiCalc *IS* available online, for free- I found this out rather
tangentially during my nostalgic kick over the last few weeks.  Go to:

http://www.bricklin.com

He also has links to other "history" sites, where you can download other
"oldies".  I had meant to post this to the list, actually- but since you
brought it up... there you are.  FWIW, this begs the question I've been asking
myself lately- just what *new* things have actually been done since those
days?  I often feel that we've been in stasis ( but at ever greater speeds and
with ever greater fidelity ) for a long time.  Certainly not up to what seemed
to be the promise of the future, as seen from back then.

Of course.
