> From: "John P. Linderman" > Brian interviewing Ken 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). Greg -- Sent from my desktop computer. Finger grog@lemis.com for PGP public key.

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/ -- Cheers, Ralph.
[-- Attachment #1: Type: text/plain, Size: 863 bytes --] 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. -rob On Sun, May 12, 2019 at 10:44 PM Ralph Corderoy <ralph@inputplus.co.uk> wrote: > Hi Rob, > > > > > https://spectrum.ieee.org/tech-history/silicon-revolution/in-1983-this-bell-labs-computer-was-the-first-machine-to-become-a-chess-master > > > > That photo is not Belle, or at least not the Belle machine that the > > article is about.

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. Doug

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.

[-- Attachment #1: Type: text/plain, Size: 1074 bytes --] Dave had lots of spare cycles. He was almost all fun. He tied his shoelaces and his bow tie every day. -rob On Wed, May 15, 2019 at 7:02 AM Jon Steinhart <jon@fourwinds.com> wrote: > Ralph Corderoy writes: > > Hi, > > > > And if others are thinking Dave sounds familiar, like me, it's because > > he was co-developer of the CARDIAC. > > https://en.wikipedia.org/wiki/CARDboard_Illustrative_Aid_to_Computation > > > > -- > > Cheers, Ralph. > > Dave was one of my favorite people in my group.
