content: not pc compatible  It was an early-80s machine (I used it in 82, methinks), shortly after the PC had come out, but before it became a standard. There were many machines like it at the time, with an 8086-compatible processor but a different memory map and I/O architecture. (Seen as a feature back then, not a bug.) Touch-screen aside, it felt like a formidable machine at first, because it ran very fast and had a nice display and keyboard. I can't remember why I gave up on it, perhaps  too much competition for quality time with it. (I loved the HP-85 which had a pen-plotter attached to it -- the awesomest thing you could ever imagine for an aspiring programmer.)
