I have seen someone posting on this site under the name Paul. Always suspected it could be Paul from Guardian. And thought he might comment on this thread. I also saw him on The Chase. He was a real contestant, not a celebrity!
Anyway nice to see and do an ‘old’ puzzle. Although I first did the Guardian one regularly in 1978, when it was dominated by Custos and Araucaria, along with others like Lavengro, Audreus, Altair.
Also to chip in that ‘old office equipment’ would have been a suitable def for typewriter in 1995! My company back then got rid of ours in 1987, we moved onto lovely Amstrad word processors (using Locoscript), and we were certainly not at the vanguard of technology. Of course it was nearly another ten years before our new machines could network....
