Advanced Energy Systems, now that I have thought more..

I worked there from around 1980 to 1983, mainly leading the
software part of the PROMT system development.  The PDP-11/34
Unix system was largely my doing, and the VAX-11/780 was
brought in just after I left.  I did drop in on a later
trip to Austin to discuss a problem with the impedance error
estimates, my fault really since as an expedient I'd divided
the error evenly between real and imaginary parts without
giving it enough thought.

I still think that LSI-11/23 real-time data acquisition and
processing system, with a modified 6th Edition Unix kernel,
was really slick.  John Quarterman (later of The Matrix fame,
the book not the movie) was instrumental in devising the
buffer scheme that really made it work; I did the scheduler.

And sometimes interesting.
