Nicely written article, highlighting an anniversary I had completely forgotten. I remember however, using these machines at secondary school, we had about 15 of them, all running Clares' Artisan art software. Some rather natty artwork was put together by the kids, sometimes there were tears when that nasty 'Filecore in Use' or 'Address Exception' error plastered itself on your artwork, hanging the machine.
Fortunately, I was able to look beyond such trifles, and learned to appreciate the Arc. I later got an A3000 then a few years later, a RISC PC, spending many lost hours playing E-type, Chocks Away, Zarch, and many more. Even did some programming on it, before using it for desktop publishing and some initial first steps onto the internet.
Happy Birthday Archie!
