In the late sixties, I worked in the IBM Hartford DataCenter as a computer operator.
The DataCenter's primary mission was to assist customers in installing new equipment
by providing machine time for testing. On third shift, my job was to run work left
by customers during the day and perform routine software maintenance. Only rarely
did customers schedule time in my shift, so the workload was generally light. During
this time, I took every self-study ("PI" for Programmed Instruction) course in programming
that I could find and was extremely fortunate in having S/360 and other computers
available for practice. Later, I moved on to better jobs in IBM. Recently, I found
this collection of pictures taken during this time and, looking at them now, wonder
if the later jobs were really "better".
A few pictures from the 1980's have been added at the end.
