My first PC was a used Tandy 1000, purchased from my brother in 1985 or 86 (or thereabouts). I spent many hours playing Sierra games, including the King's Quest series, The Black Cauldron and Leisure Suit Larry in the Land of the Lounge Lizards.
I used the Tandy for simple word processing as recently as the late 90's, after several years of disuse. I had quite a time remembering all of the commands, since it operated in DOS! I don't think it even had a mouse, just a cheap joystick for gaming. It used 5.25" floppies. Alas, it is no more; finally disposed of it last year. The Tandy was a workhorse, and it would not die!
My only experience with computers prior to the Tandy was brief forays to the computer lab in college for stats and psych testing classes. Of course, I'm quite a bit more savvy now, though I'm not very sophisticated when it comes to web design, html and the like.
Just an aside: I posted earlier this week that I planned to stop blogging. I just don't seem to have a lot of interesting thoughts to write about these days. I'm going to keep my blog up for the time being. I'll photoblog some of the time, and post thoughts when the mood strikes.
