@stux this makes me feel old. I grew up with an Acorn BBC Micro (model b, as per this machine with it's 32k memory). Its funny to think how much tech has shrunk in all my tims using computers.
This was my only experience of a laserdisc with the BBC (master in this case). I think we either had one or somehow was loaned one at High School.
