@lorry When I was 15 I was in the first ever Computer Studies O level class at my school. The practical sessions involved sending programs we had punched onto paper tape to the mainframe in Chelmsford over a telephone with acoustic couplers strapped to the handset.
The only thing I know about the mainframe was that it had 36bit wide memory - could it have been the same computer that MUD was originally developed on?

@AbramKedge yup! That was UK.AC.ESSEX.KL10. I was the last user on it, apart from Rick, the systems manager, who shut it down for the last time around me checking I'd saved everything for the 30th time. TOPS-10 was a great operating system although I am worried why my muscle memory seems to have remembered #TECO so well.
