TV programme with Ian MacNaught Davies - teams identify old technology

[NY]

Does this ring any bells...

A TV quiz programme, probably from the 1980s or 1990s, in which teams of
TV personalities often with a scientific or engineering background (eg
Tomorrow's World presenters) were given obscure objects to "play" with
and identify. These were often early versions of technology which is
commonplace today. Ian MacNaught Davies was either the quizmaster or
else a regular on one of the teams.

I remember one of the device was a *manual* photocopier. It used
xerography just like a modern photocopier or laser printer, but all the
stages had to be carried out by hand: charge a photo-sensitive plate by
waving a charged wand over it, expose the plate to a reflection of the
document, dip it in a tray of toner, place it on a sheet of paper, fuse
the toner to the paper by waving a hot wand over it. They said that a
skilled operator could make a copy every (I think) 30 seconds.

Now what was the programme called?

I sort of remember it, but there was another show that was the visual
version of Call my Bluff, where a panel had to judge what things were as
there were three possible uses suggested by celebs for each one. Was this
the one you are thinking of, or another one.

Around Summer 1989 he chaired "It's Patently Obvious" on BBC1 which was
described as the "egg-head guessing game"
