It is not a general-purpose computer, but instead a serial line analyzer: one of those things that you plug in between two uncooperative serial communications devices to divine the nature of their uncooperativeness. It's also got a breakout box built in, and you can tell it's portable because it's got a handle (think Osborne 1 for some idea of its arm-lengthening properties, though). And a 3.5" stiffy drive for saving and replaying traces. I last used it in 1995, and have moved it along with me to different offices because no-one else wants it. It works well enough for what it is, but it doesn't understand IP, SLIP or PPP-in-HDLC at all. That is the sort of stuff we need to look at these days and we have better tools for doing that. -Frank McConnell
