My mail program went nuts last week. Twice I sent a rather long piece of 
mail describing the circumstances around a Gallery picture and each time the 
mail went into a black hole and the text had to be composed again. This time 
I'm being smarter and writing and saving it first in a word processor.

OK. Don't remember what I last posted re health, but I was in the hospital 
for over a week with congestive heart failure. Made a rapid recovery as soon 
as I got home, and after a couple of weeks, returned to volunteer week at 
the Computer History Museum.

As a consequence of the loss of the Babbage Difference Engine, I rejoined 
the group that gives twice monthly demonstrations of a working PDP1 computer 
(vintage 1960), the first ?mini-computer?, in fact, the manufacturer 
(Digital Equipment Corporation) coined the term.

The PDP1 is about the size of three household refrigerators. It's turned on 
at the throw of one switch. It sold for $120,000. In the year it came out, 
the manufacturer donated one to MIT. One professor permitted ?hackers? 
access to it from midnight to morning. This was before ?hackers? became a 
pejorative term. One of those hackers was Peter Samson, who figured out how 
to make the machine play four-part music, and our demo inclueds the opening 
of a Bach fugue. The other, Steve Russell, largely wrote the code for the 
world's first video game, Space War, which later became an arcade game.

When I arrived at the Museum a week ago Saturday, I found the PDP1 team in 
the cafeteria area enjoing a post-lunch bull session. I just had to take a 
picture. We were all wearing our uniform red shirts. Note the guy on the 
right; that's Steve Russell.
