I am surprised so many of us had computers "way back when." My first was a Radio Shack TRS-80 Model 1, which I bought in '80 or '81. It had the Expansion Interface, which allowed you to bring the memory all the way up to a whopping 48K (yes, that's right kids, "K") and connect floppy drives. I started out with 2 of the official Radio Shack TRS-80 35-track single-sided drives (5.25" floppies) and later upgraded to two 80-track double-sided floppy drives (I don't remember the manufacturer, maybe Siemens). Back then, disks came in single- and double-sided AND single- and double-density. A double-sided, double-density drive was a good as it got.
My first game cost me about $10 (and I still have it!). It was a "shoot down the aliens" kind of thing, but it could simulate a human voice and say, "Die, Human!" Remember, that was before there was any such thing as a sound card. TRS-DOS (the operating system) had its limitations, and I upgraded to something called DOS Plus when it first came out. I think I even have the old disk and manual for it up in my attic somewhere.
I learned how to write in BASIC using Dr. David McLean's book. Never was much good at it, but I did write a passable work scheduling program for myself and a very elementary computer version of the MasterMind game I already had. That was a cool game. You can still buy the real MasterMind game, both the electronic and the physical versions) in stores today.
Don't remember if I still had the Model 1 by then or had upgraded to the Model 4P, but I got a 300 (!) baud Hayes modem as soon as I could and signed up for CompuServe. Kind of an early internet. Later got a 1200 and then a 2400 baud Hayes modem. Still have them, mint condition. Bids, anyone? Anyway, I joined and experimented with several BBS's those first few years, but CompuServe was by far the best and most user friendly. Wonder if they're even still around? I think my UserID was something like 71143,54. Weird...
Anyway, thanks for the memories. I haven't thought of that old first computer of mine in years. I eventually sold it, and I'm sure it's in somebody's attic even as I type this. Model 1's still show up on eBay once in a while, and I know the Smithsonian has one.
