>Not completely. There's still stuff out there. There's a LOT of traffic in the 'first laptop' the Model 100 - look on eBay. They get used for remote data gather and lab controls - along with another classic from the past, the Timex-Sinclair 1000 (yeah, I had one of those too - still do). I have a friend who's father is a professor at a local college, when they disontinued the TS-1000 he bought up literally CASES of them to use as controls for his lab equipment - pretty handy little boxes as the expansion slot on the back fully exposed the Z80's pins, it was like a CPU development system you could program in BASIC.

I still have the Centronix interface for the Sinclair ZX Spectrum; it's a dongle which plugs onto this expansion slot, and ends with a regular printer cable. Now writing a driver was a different matter; you had printer buffer space which was supposed to hold one pixel line (256 bytes) for screen dumps, but would go unused if you wrote your own. I remember it took me two days to replace two drivers (graphical and characters) which were published in a magazine, with one combined which would fit into the same space. That was fun :).

Of course, I had a full keyboard with a steel case (actually the motherboard fit inside it), a reset button and a joystick port (plugged in parallel to keys 6 to 0 of top row). There was a problem of how to isolate the board from the bottom of the case, but that was solved by rubber pads (the ones used for faucets) and a few ballpoint pen outer shells cut to proper lengths, to keep the distance from the top part.

Last time it worked, its video output was losing it a bit, and I think it needs a new AC adapter, or at least a cable for it. It's probably one of the oldest - the serial number is 6xxxx, five digit only, and I think there were about two million of those made.
