The last 3 weekends we fixed all DRC errors, and then we went through an old list of things to do and check, which we're almost done with too.

Managed to gather some time and energy to work on the SuperVidel. :) Just finished the rework of the DAC-layout, which was the last big change on the board. Now there are just some minor signal vias left to place. Then of course we have to do a thorough check of the entire board...

If you're wondering why nothing has happened lately on the SuperVidel or anything else, that's because our regular jobs currently demand that we work evenings and weekends to get things done for a deadline soon. Hopefully things will get a little less hectic in October.

This weekend we were at Hackspett 2011 in Falköping. It replaces the old Atari-only event NAS, but is still organised by SAK. Other platforms were invited, but we mostly saw the same old guys who mostly brought their Ataris, but also the odd Amiga, C64 etc.
During the event we helped Pep input the timing register values for a 1920x1080p 60Hz (mono to 32 bits) resolution into his SV_XBIOS.PRG. This resolution is now selectable from his modified TOS resolution changer (looks like the original), which uses Vsetmode() using the two-byte modecode. So we used 1920x1080 during the party in XaAES under Mint, on a DVI TFT screen. To get this high resolution we used the so-called VESA CVT-RB (reduced blanking) timing, to reach high resolutions with a reduced pixel clock (138.653MHz in this case). Our 24" TFT had no problems with this timing on the VGA input either, so as long as you have a resonably new TFT screen, it should work for you.
Pep was otherwise deep in his work rewriting his SV_XBIOS program, and Henrik was busy coding other things on his falcon. I (Torbjörn) added a new bit to the SuperVidel copy of the 0xFF8266 register, which controls the colour depth of the Videl. The new bit enables 8-bit chunky mode in Videl resolutions on the SV output. This way you can easily change a current game/demo which runs in 8bit planar mode, into an 8bit chunky mode application, so you can lose the costly chunky-to-planar conversion during each frame... :-) All you need to do is set this bit to 1 when writing to the 0xFF8266 register.
