Apparently after what I've heard, integrating the delay lines was a huge problem Perhaps that at that time it was not something that could easy done. -----Message d'origine----- De : firstname.lastname@example.org [mailto:email@example.com] De la part de Gerrit Heitsch Envoyé : mardi 1 novembre 2011 18:32 À : firstname.lastname@example.org Objet : Re: C16/Plus4 On 11/01/2011 06:09 PM, Didier Derny wrote: > Hi, > > In France i was unthinkable to sell a professional computer without > A French keyboard and printers able to print the accents. > > > Yes SECAM was too complicated to be integrated due to the delay lines. > I think that Commodore tried to evaluate if a VIC II SECAM was possible > But apparently they gave up when the saw that they had to integrate delay lines. If I understand that right it would have meant some additional memory in the VIC-II. You don't need to use an analog delay line, you can use a digital one as well. But it would have meant a major design change (plus validation and testing) compared to NTSC and PAL. Obviously they thought it was not worth the effort.
