Subject: The ongoing question of display ratios

--=_NextPart_Lycos_0187451087999136_ID

You may remember the long conversation I took part in earlier this year concerning
the TV display of 
BBC/Electron machines and whether or not the pixels are genuinely square.
Concerning this I put a general 
appeal for real world measurements on my website and have received the following
reply from Stephen Pearson:

"I ran the program on my Acorn Electron.The measurements you were after is
34.5cm across and 30cm high 
(approx). Your proposed ratio seems spot on."

The program to which he refers is:

       10 MODE 4
       20 DRAW 1279, 0
       30 DRAW 1279, 1023
       40 DRAW 0,0

My propsed pixel ratio is 12/13 times as wide as tall.

Hope this helps!
