IXI

The invention

Imagined by Kane in November 1979, at 23.

He then developed it with James Campbell, and together they went on to design and build solid-state digital media recorder/players. The first patent was applied for in 1981.

After years of development, and following the building of four prototype models, the fifth pre-production Pro recorder/player model went on sale at the APRS exhibition at Olympia, London.
