Mid 1970's to mid 1980's

In this time frame my computer work included learning and teaching assembler language and operating systems for the IBM 360/370/Etc systems. It also included learning and teaching COBOL, PL1, BASIC and Pascal, at least at the introductory level.

My focus then was more on teaching, sailing and photography than on computer programming. I did manage to sail on all of the Great Lakes except Lake Michigan, and to win a first prize and some Award of Merit prizes for my photography . Both of these hobbies were focused on the technical aspects of their respective subjects, the photography including color darkroom, and the sailing including racing [and eventually sailing in Europe, although I missed an opportunity to do an Atlantic crossing!]

Mid 1960's to mid 1970's

I took my first computer programming course in my final year of university. The Computer Science Department hired me upon graduation. My first project was lead programmer on a team writing a COBOL compiler for an IBM7040 computer. Subsequent projects included writing an ISAM system in assembly language on a DEC PDP-10 to allow Fortran programs to use direct access to data files, writing a small operating system to allow graduate students to program a DEC PDP-8 to control a robot, design and implementation of a programming language to allow artists [yes, artists!] to use a DEC PDP-8 to generate graphics images on a CRT, and the design and implementation of an interrupt driven kernel for an operating system for the DEC PDP-8 computer. The latter work formed the basis for my Master's Degree thesis, and for a technical report by the Computer Science Department.

I completed two contract jobs for a local computer service bureau that required writing assembly language programs for a Burroughs B500 to read paper tapes produced by a Friden business machine, and one contract job for the same company to debug a large, complex COBOL program "by Monday morning at 10.00 a.m. or else we will lose the account".

Mid 1950's to mid 1960's

I was a scientist even back then! As a boy I sold New Liberty magazines door to door in my neighborhood, and with the proceeds I bought a ChemChraft chemistry set. Chemistry was my hobby during grade school and high school, funded by my jobs delivering newspapers, and working as a delivery boy for drug stores. The most exciting event of that era was the launching of the Sputnik satelite!
