Eric's got a KL.  If he had a KA, I would have tracked him down and beaten
him to a pulp to lay hands on it--and we're friends.

Nope.  They moved to Albuquerque as soon as the deal with MITS was done.
(Ed Roberts hired Paul as his VP of software development on the spot.)
They rented time from the Albuquerque school district, whose -10 had
unused capacity.  (Development of the BASIC interpreter was famously done
using the Harvard KA-10.)

They went from renting time on others' systems to owning their own when
they moved from Albuquerque back to Seattle.  Their first was a KS under

I have all this not merely from Paul's book, but from another friend who
was Microsoft employee #11 (who appears in the famous picture) and others
like David Bunnell at our grand opening.
