Mine is an interlaced 512x512 in a 8296 and it works fine on the inbuilt monitor. It is quite a slow phosphor monitor so the interlace flicker is not too noticeable. This monitor timing is very different though and on mine I need to tweak the v and h sizings a little because I'm missing the bottom 30 pixels or so when in hi-res mode. The horizontal size is also very compressed, here is a screen image which is plotted from 0,0 to 511,511. http://inchocks.co.uk/commodore/PET/GFXBoard/DisplayAlignment1.jpg Rob On 24/07/2012 00:02, email@example.com wrote: > Hi > > The board I tested in 1982 was just not working in 512x512 > It was using "interlaced" lines so we just saw flickering > you could be see sick after having watched the screen for 1 mn :) > > perhaps that it worked fine with a new release of this board with the > connector for an external monitor. > > -- > Didier > > > > > -----Message d'origine----- > De : firstname.lastname@example.org > [mailto:email@example.com] De la part de Rhialto > Envoyé : lundi 23 juillet 2012 23:51 > À : firstname.lastname@example.org > Objet : Re: PET hi-res board > > On Mon 23 Jul 2012 at 22:44:52 +0200, Christian Dirks wrote: >> Am 23.07.2012 21:39, schrieb Steve Gray: >>> [...] I don't know of any real software that would use it.
