I remember we had three of these on trollies in my primary school - two had colour monitors, and one had a black and white monitor.
Somehow I managed to network/schmooze/brown nose my way into becoming a "computer mover" when I was in the 5th year with two of my friends. We were tasked with moving the computers first thing on a Monday morning into a new classroom, who would then have it for a week. We'd plug it in, turn it on and load up the correct disk that the teacher wanted to use.
I think that's where my love of computers came from right there. They were really good computers for their time. I gather that they were expensive, which is why they didn't find their way into many homes. However, a generation of British children did indeed grow up using them.
