The SX1000, from Italian company JEN Electronica s.r.l., came onto the market in the late 1970s, and could be bought through home-shopping catalogues and music shops. It was built down to a price, and many were sold throughout Europe and beyond. In 2002 Neil acquired a non-working SX1000 and set about reverse-engineering its internals to try to get it working again. This talk walks us through that journey, from the initial fault finding, to the enhancements and updates that were developed and tested, covering MIDI, filters, oscillators, and the bottom end.
