Going OT for a moment here (sorry Jay) over xmas I was talking VCRs with my
Missus and went off searching for the very first one I used back in '83-ish,
a Ferguson Videostar. I was surprised to re-learn that the channel tuners on
that were all the 'spinning wheel' type. There was one on fleabay for 10ukp
but I wasn't allowed to bid.
