If one is building a TV which already contains the expensive components required to decode PAL, tweaking the constants to also decode NTSC is cheap and economies of scale may make it cheaper than to make the set PAL-only. It's been about 20 years since I last saw a nominally PAL TV which couldn't also decode NTSC.

NTSC I remember getting my Atari 1200XL back in 2000 or thereabouts and was surprised to find I got a good picture on my 1996 Toshiba TV. I think as soon as PAL TVs gained SCART sockets and RGB composite they also got the capability to handle NTSC signals. Even my cheapo Fuji portable will handle NTSC and quite probably SECAM and others. If I ever get my hands on a Thomson TO7 I'll be able to try it :) Cheers -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest home computer collection? w: www.binarydinosaurs.co.uk t: @binarydinosaurs f: facebook.com/binarydinosaurs <http://www.binarydinosaurs.co.uk> On 7 March 2018 at 08:06, Terry Stewart via cctalk <cctalk at classiccmp.org> wrote: > Hi, > > The PAL vrs NTSC TV standard complicated things when collecting home > computers from other countries. > > In New Zealand we are on PAL.
