I am retired from a computer business that I owned in Atlanta, GA. In this business I sold all types of personal and business computers which for the most part were IBM Clones. I also wrote business and medical office software which was based in Foxpro (a database language). My first computer was a Motorola HEP kit, which was similar to an altair or KIM1 single board computer. I designed a light signaling system for doctor's offices and manufactured my own PC boards in my basement. I sold that business and went full time in the computer business. All of my programing experience was and is self taught. I enjoy tinkering with electronics and computers in general and that I why I purchased a Raspberry Pi. My other programing experience has been with PIC controllers from Microchip, and I designed an elevator controller using a PIC Micro controller.
