I have been programming since I was 15 and our computer at the time
was a teletype connected to a computer, I think at Bell Labs. It spoke Unix and Basic. The input could be a punch card. One of my fellow programmers had a

chess playing program which blew my mind… This was
the 1970’s and there was no internet! I was hooked ever since. I programmed in college 1980’s on My HP 65 calculator for fun and class. Also, for Bell Labs at the Homdel site which had the radio Horn antenna which discovered the Black Body radiation The program was used for utilitarian programs related to pointing of the antenna etc.
I became a physician and recently, became interested in how programming is done now. I have some ideas for AI imaging in medicine.
