I have not heard back from the U.S. distributer yet. I can't believe anybody would pay $2,200US to convert a video signal. You could obviously buy a new monitor for far cheaper. Is the goal og you RGBI-to-VGA project to produce a comercially sellable product, or to produce a design that others can work from to build it themsleves? John

Maybe I misunderstood the amount, but the sales guy proposed a lower cost device for 500$. He said he would email info to me. My project is just for myself. I never intended to sell any since the interest was so low. At best, I was going to release the schematics and the Olimex work order number to get your own PCB and then you can build it yourself. This depends on your skill level and what tools you have, of course. Most parts can be had at Digikey and the other parts I can order through work since they need the old-school distributor/purchase order thing. Programmed PICs I can supply. If my tests on the genlock chip suceed, I can write some more code to configure the main IC and maybe start seeing some VGA signals soon. This is just a hobby for me though, so if I get drunk this weekend, nothing will get done, again... You seem to have a fairly urgent need of such a device. (BTW CGA and RGBI should be the same thing, but the IBM CGA monitor did some tricks to the brown/dark yellow color that I'm still not sure the C= monitors did. At worst, you'll have one color from the 128 not look exactly right.) I think the high cost of their device reflects the amount of work required to get such a thing working and the small market for one. You can get NTSC to VGA boxes for less than a 100$ cdn.

Currently I have all of these operating off of my Dell 2407FPW monitor. * My main PC running XP (via VGA) * A PC running 64HDD (via VGA) * A C128D (40 column via composite) * An Atari 130XE (via S-Video) The only think I cannot get to work on the monitor is 80 Column output from the C128 RGBI port. From previous threads it seems like my best option may be to try and find or create a RGBI to RGB Component interface. The Dell 2407FPW support RGB Component input. I'm not really a hardware guy. I can do simple things. But, I think I'm better off trying to go off-the-self if possible. John

You can get mediocre monochrome composite output from the RGBI Port on Pin 7. You'd be missing out on the excellent color, but at least you'd be able to display the information. |
