I'm still wondering if you can wait for my project to come to fruition. At the moment the genlock chip is being put through its paces. I'd like to know if DVI output is important. The other chip I could have used is a AL251 with digital RGB outputs which could be fed to a DVI encoder, but that's a bit beyond what I think can be done with a two layer board. Did you look at my RGBI to VGA page?

"Supports [...] CGA [...] Input" So, you do *not* need an RGBI to RGB converter. It doesn't look like these devices will be cheap, though. -- Martijn van Buul - pino(a)dohd.org - http://www.stack.nl/~martijnb/ Geek code: G-- - Visit OuterSpace: mud.stack.nl 3333 The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!'

Yes, I was hoping this was correct. I have read in several places that Commodore RGBI and CGA were compatible. So, I thought this device might work. I have an inquiry to the companies U.S. reseller to get a price quote. I'll let you know how expensive it turns out to be. John
