Hello, I have pulled together a website with links to resources and
information on SEL, or Systems Engineering Laboratories.
http://mnembler.com
SEL was a computer manufacturer in the 60s and 70s which later was acquired
by Gould and then Encore. They made many major innovations and were
instrumental in the success of the Apollo program.
The website is still a work in progress, but I did want to share it with
yall.
