Wow, that's really great! I'm somewhat ashamed to admit that I didn't get
Ken's shirt until 30 minutes into the talk....

Loved the talk, and getting more information about Belle.

Saw the shirt right away, even understood the greek.

Ah, thanks for that. I had intended going (since I've never met Ken), but
alas, my daughter's family had previously scheduled to visit that weekend, so
I couldn't go.

The 'grep' story was amusing, but historically, probably the most valuable
thing was the detail on the origins of B - DMR's paper on early C ("The
Development of the C Language") mentions the FORTRAN, but doesn't give the
detail on why that got canned, and B appeared instead.

I was also quite surprised by that. No mention of BCPL...

Great video, really loved it.

Can you clue in those of us who are less mathematically (or whatever)
inclined?

Thanks,

I found that particularly clever.  It's not Greek, as far as I can
tell, but who cares?  You are not expected to understand it.

Of course, the real clue was the code (Sixth Edition
/usr/sys/ken/slp.c, lines 325 and on).

That photo is not Belle, or at least not the Belle machine that the article
is about. Belle is in a white wooden box about the size of a bar fridge,
with a stylized blue and gold logo on the side.

Here's a picture that matches.  http://www.chessgames.com/perl/chessplayer?pid=23230

The one in the article seems to come from
http://www.peteradamsphoto.com/belle-chess-machine/

Ken tells me (and I now remember) that the photo in the article was of a
sort of input device, a board built by Dave Hagelbarger that sensed where
the pieces were so could digitize moves.

My extremely fuzzy recollection is that Dave had an LC tuned circuit in the
base in each chess piece and an antenna coil underneath each square on the
board.

About the creator of the sensing chessboard: It was Dave Hagelbarger,
as Rob said, not Joe Condon as I wrongly recalled.

And if others are thinking Dave sounds familiar, like me, it's because
he was co-developer of the CARDIAC.

Dave was one of my favorite people in my group.  He was the first person
that met who was absolutely brilliant in technology but couldn't spare any
cycles for things like tying his shoes.

Another interesting thing that he designed was the keyboard that eventually
got hooked up to the music playing version of the digital filter setup that
Hal Alles and Jim Kaiser designed.  It had a ribbon cable the length of the
keyboard that was fed by a binary pattern, and each key had an antenna that
moved across the cable when it was pressed making it possible to determine
how far a key was pressed down.

Dave had lots of spare cycles. He was almost all fun. He tied his shoelaces
and his bow tie every day.
