I sold my paintbox for £12 in 1988. It ran on a BBC Archimedes 310 in the shop window of the computer store where I bought it doing abstract expressionist artwork to show off its various calligraphic and airbrush tools in full colour. To put this in perspective Photoshop 1.0 was available back then, ran on a more expensive Macintosh and was black & white. I sold 4 copies and the shop took a cut.
