There was no shaking him off, so I followed him down to his car and we drove to this sleazy little bar in the Negro part of town. As soon as we sat down in a booth, Len borrowed all the nickels I had, put them in the jukebox and pressed the levers for a lot of old Louie Armstrong records.

"Sorry, kid," he said. "I know how you hate this real jazzy stuff, but can't have a reunion without music, and there isn't a polka or cowboy ballad or hillbilly stomp in the box. They lack the folksy touch on this side of the tracks." Len has always been very snobbish about my interest in folk music.

A machine that plays chess? That was interesting, I said.

"Didn't tell you the whole truth the other day," Len mumbled. "I did work on the Remington-Rand computer, sure, but I didn't come to IFACS directly from that. In between I spent a couple years at the Bell Telephone Labs. Claude Shannon—or, rather, to begin with there was Norbert Wiener back at M.I.T.—it's complicated...."
