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.
