This trip down memory lane makes one feeil old. Anyone remember
teletypes with punched tape?

Of course. My favourite paper tape story. At AEE, Winfrith, we did
serious computing on the IBM704 at Risley in Lancashire. We would type
the program onto paper tape and run it though a teletype to send it by
phone to Risley. At their end they would punch it out and to check that
it was ok they would send it back. At the Winfrith end we then had the
original tape and a copy and we would hold these up to the light to
check for errors. If there were none we'd phone Risley and say yes ok
go ahead.  This was a communication protocol, yes? Later we installed a
punched card system so we could put the program on cards and fly them
to Risley by plane.


I assume you never worked with the folded papertape used with the DEC PDP-8! coded in ASCII. Years before we used an Electrologica X-1 with papertape coded in EBSDIC!You could edit the tapes with a manual punch and nontransparent sellotape. We thought punched cards were old-fashioned!.
