This Philips Personal Music Composer PMC100 is pretty awesome: Launched in 1986, it had a nine-channel FM synth with a 100 presets, a membrane keyboard, 8k of ram, a built in cassette recorder, MIDI and buttons for a strap. It's hard to imagine just how fly you'd look bouncing around a stage wearing one of these. It was designed by British PC music pioneer Lyndsay Williams, who claims to have designed the first ever PC soundcard, for an Olivetti in 1987 (this powerpoint presentation tells his her full story). If you fancy a PMC100, this one is currently £45, or there's another one here in Germany...
