My dad worked at BT and used to take me to different exchanges at the weekend normally on Saturday mornings. I guess he claimed a day in lieu for working a couple of hours and then we went for lunch or pottered around the shops. In there were all sorts of interesting things. Piles of discarded electronics of various eras. Several computers and terminals for connecting to mainframe systems. I remember a Sinclair QL and Amstrad PCWs I think. He would let me play around with the terminals, no idea what OS was on there maybe VAX or VMS, use the printers and Microdrives. I was really interested in all that stuff as a kid but didn't really have anyone to learn from as my dad was more of a lineman, having started in the Royal Signals. Fun times!
