My name is Jack and I have just joined techspot. I am retired from the aerospace industry after many years. When I was discharged from the Airforce I did interview for a job with the first digitial computer ever built at St Paul Mn. I forgot the name of the company but that was in 1954. It filled a room as big as a warehouse. It had banks and banks of racks of diode tubes and flexawriter for IO. I didn't get the job. My first computer was the Apollo guidance computer which I as primarily a hardware engineer,but I did write several diagnostic programs for it. We had only 11 instructions to deal with. Later I started working with automatic test equipment for the A7 aircraflt equipment. They used Basic and atlas as programming languages. Now I just do programming for my own use and use only Turbo basic as my language.
