I started high school in the fall of 1976 at South Portland High School.
We had a PDP 11/70 running RSTS/E Vo6B on 256KW of memory with two RP04 hard drives.
My first year in high school, my algebra class assigned us to write basic programs, solving certain quadratic equations. This was my first real exposure to computers. Over the course of high school, I spent a great many hours working on that computer.
During the Summer after both my Junior and Senior years I worked for the school as a programmer/operator. I handled the daily and weekly system backups as well as maintained systems programs with updates. From a programming point of view I worked on data entry and analysis programs for the high school, school department and the police department.
RSTS/E V06 was written in assembler, however most of the commonly used system programs were written in Basic-Plus. I believe it was in my Junior year, we got a version of Pascal from OMSI. The computer also had COBOL for the business classes.
I wrote mostly in Basic-Plus, although I did take a class in Pascal and wrote some in that. I wrote one small program in Cobol to read cards from the card reader and put them in a data file.
