Somewhere between 1995 and 2000, I was sent to teach a pSOS+ class to Westinghouse engineers in Savannah, Georgia.

There are two versions of this document. Both contain the same technical descriptions.

For a short, four-year period in the 1960s, the man sitting to my right was a High School teacher. I knew him for two of those. None before, and none after.

Once upon a time, there were three RTOSes named VRTX, pSOS and VxWorks.
