At Ken Bowles retirement from UCSD (Ken was the lead of the UCSD Pascal
Project) he related a story that IBM came to UCSD after being ‘rejected’ by DR
to see if the Regents of the University would license UCSD Pascal (the OS and
the language) to IBM for release on the new hardware IBM was developing. The UC
Regents said ’no’.
He was quite sad that history took the very different course.
