I am currently mainframe computer operator, and been doing this for 20+ years.
Before that, 12 years as computer maintenance in the USAF. Usually waiting for the operators to break something so that I could fix it. The systems I was trained on were: AN/FSQ-7, Univac 1050-II, IBM 360 Model 75J, and IBM 370 N12-N8.
I was stationed in a few places, notably, 21 months in Australia. Me home away from home.
I am a licensed private pilot and aircraft maintenance technician. And with that I was an Aviation Parts manager at a small airport FBO with small charter airline hauling freight for UPS and USPS.
My interests are mostly, sailing ships, aircraft, modern ships, spacecraft, real science and science fiction, and cad drafting.
So, why am I here? Mainly to find a way to find enough income to fix my house to keep it from falling around by ears, and to build a decent retirement. And maybe enjoy it while doing so.
