Woz story on UCSD Pascal P-System

Woz told me a story in email: "Apple at one point turned down the Pascal P-System. That very evening Bill Atkinson and myself hopped on a plane at our own expense and flew down to UCSD, where the P-System had been developed. We stayed with developers in their lab that whole night and incorporated Apple II disk routines and graphics routines. We brought it back and showed how useful and good this Pascal system was and Apple changed its mind."

But no longer. Programming has become a science, where you need to be a rocket scientist to just to do something simple!
