Re: Where do you draw the line ?

In the end it is always what makes it fun for you. Personally, be it your H5 or Pavel's (hopefully one day finished) Falcon030NG board, my motivation for purchase is / will be always the same - the security of having a modern motherboard without all the faults and cheap workarounds so I can enjoy my...

Re: Atari TT: Optimal OSSC settings.

Would any of these work with TT-High that's been converted to VGA? I guess the real question is; do they support 1280x960? Just tried on Medusa -- 1792 pixels per line does the trick. There's a slight moire pattern (its visibility seems to depend on the monitor brand, too) but I couldn't make it go...

Re: Atari TT: Optimal OSSC settings.

Not to slander the OSSC or anything but with the Medusa it's a matter of three settings... basically one, just set the pixel clock to 1024, double pixels/lines and done. My TT has never produced a better picture.

Re: Two Falcon 030's Rev B & Rev D/C

@kohli79's photos is a good example why those PCB s/n shouldn't be taken as gospel. It's a normal (Atari) board with their upgrades. I guess they were recasing / mounting Atari boards in parallel to producing new ones.

Re: Two Falcon 030's Rev B & Rev D/C

Hmm so your case looks like the Atari one? I guess you are sure that this is the original one? It's possible that C-Lab have been producing new motherboards and putting them in old cases (which seems unlikely, your case has a s/n from 10/94) or that the last batch from atari (09/1994) already had th...

Re: Two Falcon 030's Rev B & Rev D/C

Thanks! Are you sure the rev.B isn't a C-Lab MK2/MKX Falcon? The board revision and serial number would imply that.
