I don't think RPG (Dick Gabriel) had anything to do with the actual Symbolics corporation, other than perhaps cheerleading from a distance. (I was working at MIT at the time, using the original AI Lab LispMs. Loads of fun.)
He must have been a symbolics founder like Dick Gabriel? (Dick now does the IT conversations stuff, and seems like a good guy to advise and mentor a new generation, except sadly we don't seem to want to learn from the past in this industry).
Personally if I meet someone who was around in the 80s, spent time with xerox machines, or (sometimes) at some great lab/company, I plant myself, and hoover their brain dry. I can't get enough of software history, there is gold in their experience. I just wish it was more common.
I love reading the comments on Yegge's blog. They all read to me like, "Wow, this guy just wrote 10000 words about himself, and now I feel useless. If I reply to him nitpicking a point or two, I will be as awesome as him!!11!".
