The "old guard" (to me) consists of: Ken Thompson, Dave Slate, Hans
Berliner, Fred Schwartz (chaos), Ed Kozdrowicki (Coko), Jim G. (Tech)
Tom Truscott (duchess), Monty Newborn (Ostrich), Tony Marsland (Wita and
Awit), plus Donskoy and a few others. Later, the Spracklens, and
Dave Kittinger and Richard came along, followed by Ed and the rest. I
probably fit in with the first group since I had a working program in
1968, and played in my first ACM event in 1976.

I think Larry did the book for Mac Hack and Greenblatt.
