I have worked with computers, off and on, for over 38 years. When I graduated from college in 1976, I had tried to fashion my own MIS degree, which, of course, didn't exist then. My first real experience with a "computer" was carrying punch cards to a window to have someone run my program on an IBM 34. I had met a graduate student who told me how to modify the jcl (job control language) to make my programs turn around faster. Next was a programmable calculator, the Victor 4900, and a word processing machine, the Burroughs Redactron, both of which were being sold by the office machine company I worked for.
The first "real" personal computer I owned was an Atari 400xl. That was soon replaced by an Atari 800xl - of course modified with Claus Bucholtz's memory upgrade, and then an Atari ST with a daughterboard sporting the NEC V15 chip which allowed me to run MS-DOS. I would have loved to have an IBM computer, but I couldn't afford the $5000+ it cost back then (clones were selling for that much in 1983). At the same time I was learning the intricacies of the Burroughs B-27 computer that was being used by U-Haul and subsequently I found a computer job supporting the Burroughs B-28 used by county governments. I finally cut my teeth on IBM compatibles when I started replacing banks and credit union's terminals with pcs, around 1991. It was fun back then - DOS based, with multitasking provided by a program called Software Carousel. The only real claim to fame is that I earned a MCP for Windows 3.1, and I am a Novell CNE.
After working for a bank for 4.7 years as their IT Manager, I started my own computer support business in 2004 and have been mostly helping individuals and small business clean up their systems. I am semi-retired, but still have a big book full of satisfied customers.
