Frank -

    I am, it's first draft is roughly what I get when I filter my
outbox.  The chapters on "memoirs of sci/tech" are in the
"recipients:Friam" stream... this collection may very well also be the
primary contents of many's TL;DR folder here.

    I would appreciate a second memoir from yourself covering the years
(and anecdotes) including running Paul Erdos out of the Berkeley Campus
Library each night and the belly of the ATT and CMU (and???) beasts...
to complement the not-too-long-after-wild-wild-west days in NM.

    My friend who is no more than a couple of years younger than you who
grew up in Las Vegas and Amarillo recognized a lot of familiar "color"
from your memoir.  He got lucky and ended up at MIT in the early 60s...
