I am embarking on a series of articles regarding my ventures into remote
imaging via meteorological satellites - I began receiving images from
home-brew equipment back in the 1970's.

One small technical point, would anyone know when the Met office stopped
using the wet paper facsimile machines for chart and imagery read out? I
remember visiting the Cardiff Met office and carrying off some of those
slightly fuzzy purplish print-outs, but can't quite remember when that
would have been.

Thanks in advance for any assistance.
