ProgMetalMan Posted January 21, 2015 Share Posted January 21, 2015 Has anyone attempted to put one of these behind their ANTIC? It would probably work, if someone's willing to fork out the cash to try it. Quote Link to comment Share on other sites More sharing options...
Rybags Posted January 21, 2015 Share Posted January 21, 2015 I've got in my 800XL for the last 5 years or so. AFAIK they can be coaxed into working on a 5200 but not sure if any pre-req's like different core flash is needed. In any case it's a pretty pricey way to get a better picture from a 5200. And it's pretty unlikely that any software that takes full advantage of VBXE will make it through to the 5200. Besides that, you need a 16 KHz RGB monitor such as an Amiga 1084 and such monitors are becoming rare. Alternatively a modern LCD that has full SCART input or can otherwise handle 16 KHz RGB but they're not real common either. But there's not really any other RGB alternative around, there probably will be RGB, Component or even HDMI addons in time but not at the moment.

See: http://mikejmoffitt.com/articles/0032-tvrgb.html. I was going to try to do this on my small '98 Trinitron (I know what not to probe and how to discharge a tube so as to not fry my Atria) but managed to screw up my Genesis (which was the easiest source of RGB for testing) trying to pull RGB from the board. I'm pretty sure it's a faulty cart slot connection, though, so I have to goof around with that some more. How much cheaper can it get? NESRGB boards are around that price, and do more or less the same thing. It seems that in order to get any sort of output beyond S-Video (with its low chroma resolution), the GITA will have to be emulated with an FPGA.

Rybags Posted January 21, 2015 Share Posted January 21, 2015 That's a pretty nifty hack to patch RGB into the TVs OSD system - but the problem is it'd be beyond most people and we don't all own the same types of CRT TVs. The alternative to full-blown GTIA emulation has been discussed. We are lucky in that GTIA gives us fully digital Luma and Sync. The colour signal is the problem but the colour pin from GTIA gives a square wave that's phase delayed dependant on what colour is needed. By tapping those signals an addon device could generate RGB or Component video, and at lesser cost than VBXE. If it could be done in the under $80 range IMO it'd be a hot seller.

Gaztee Posted February 19, 2015 Share Posted February 19, 2015 Would love an rgb option for the 5200. As this is now possible for the colecovision is this doable on 5200? Would love to run this baby through my framemeister Quote Link to comment Share on other sites More sharing options...
quylein Posted February 19, 2015 Share Posted February 19, 2015 That would let me utilize the unused pins on my snes multiout adaptor in the future. Quote Link to comment Share on other sites More sharing options...
ApolloBoy Posted February 26, 2015 Share Posted February 26, 2015 Someone here managed to mod their 5200 with a VBXE, AFAIK it's pretty much the only way to get RGB out of an A8 or 5200. I've thought about getting one but I don't see myself using the VBXE's expanded capabilities much if at all. Quote Link to comment Share on other sites More sharing options...
bbuchholtz Posted July 12, 2015 Share Posted July 12, 2015 I'm also interested in this. Does anyone have a copy of "VBXE5200.doc", that was originally in this thread: http://atariage.com/forums/topic/183821-rgb-in-5200 -Brian Quote Link to comment Share on other sites More sharing options...
