Unix History in 2 paragraphs or less.  :-)

Ritchie and Thompson sold the original Unix project, in PDP-7 assembly,
to their Bell Labs department head as a document processing system;
roff was the first full scale Unix app.  It went so well that they
ported it to the PDP-11s, and (I think) also into C at the same time.

It did end up running switches, and runs the 4ESS and 5ESS to this day,
on AT&T 3B20D dual-processor machines with hot-failover at the
instruction level (I think).  The earliest switch it ran?

I *think* it might have been the 1A ESS, back around 1982ish or so, but
I'd have to check.
