To keep it simple, I'll just list my computer/software experience.

1970 learned BASIC on an IBM 360 timeshare terminal while working for MCI when we consisted of about a dozen people.

1978 bought an Apple II Plus with a floppy drive [140kbytes!! wow! ha ha ha].

1978-1985 sharpened my programming skills in BASIC, Forth, assembly language, and Pascal on the Apple II which I upgraded along the way. I was a member of the A.P.P.L.E. and submitted several programs and articles to various bulletin boards. Received a couple of awards.

1985 bought my first PC.

1985-2000 Eventually tried Windows 286 and tossed it, then finally bought Windows 386 and kept it. Studied and passed the MCSE certification. Added C and C++ to my repertoire and started building programs for Windows for Workgroups 3.11. Got a couple of awards for utilites I wrote.

2000 I retired from my 'day job' in electronics and went to work full time as a programmer/analyst and network engineer.

2000-2005 worked on web and client server software. The applications included web and desktop based learning software including testing, progress reporting, etc.

Worked with another guy in creating a web based parts catalog on an SQL Server database from the ashes of a web fiasco they bought based on MS Access. I then built a massive MS Word VBA based catalog generator for them that took the SQL database and generated their 1,000 page catalog.

2005-2007 worked as a contract programmer. Supported magazine fulfillment and billing via web apps in ASP and ASP .Net. Upgraded my skillset to the .Net universe.

2007-2010 worked for a large manufacturing corporation's shop floor software support. Analyzed and mapped out the two dozen applications and two dozen flat files plus a half dozen SQL Server db's that supported and controlled the entire manufacturing process. Created a math intensive app to convert customer orders into machine control data.

2010 - retired... sort of... *grin*
