Thanks, Jeffrey - just proves anyone can do it if I can.
For my next trick...Teletext. Please see pics.
I've just coded one page into PROM 0 (1st PROM of the colour pattern set) as a test. The page is a coded reconstuction of an image from the excellent, and very handy, gallery here -
http://teletext.mb21.co.uk/gallery/oracle/end-itv.shtml
Possibly the first time that particular page has been run through a real Teletext Decoder since 1992. I've also posted a picture of the TV's decoder set to 'Mix', just to prove it's real teletext and not just an image!
Time for a lie down.....
