I was at school and among the Acorn Archemedes in the computer room (so called because it was full of computers!) was a newfangled piece of kit. It looked like a vinyl LP player, but had a shiny disc on it the size of an LP. We were told not to go near it , presumably because of the laser. When the teacher left the room at lunchbreak some of us did take a closer look, but being about 12 at the time (and having never owned a CD player at that time) I was rather clueless as to what it was. I know laserdiscs are largely used for films (hence why I can see why Jay thought they were off-topic), but I believe this one had some sort of software on it. Not sure now whether the laserdisc player was hooked up to one of the Archemedes, or some new computer. Almost all the computers at school were Acorn Archemedes, except for a handfull of BBC's.
