opcode Posted March 29, 2017 Author Share Posted March 29, 2017 True, but wasn't it used only in 10-bit mode? The word length isn't all that makes a processor better. The Z80 was a much more mainstream processor than the GI PLC processor in the INTV. The clock speed on the CV was about 2X the INTV and it more closely resembled the systems in use in the arcades by Midway, etc, so games ported resembled their arcade counterparts more closely. Perhaps Z800/Z280 compatibility would be a good choice here? It came out about the time the CV was discontinued. I would think that would be a natural progression even though that processor really never saw the success of the Z80... There are a number of cool replacements for the Z80, Z800/Z280, Z380, eZ80 (which seems to use the R800 core), Problem is that they aren't execution time compatible with the Z80. If all CV software was well behaved, that wouldn't be an issue. So the only option is to offer a Z80@3.57MHz. Of course that is too little for Prometheus, On the other hand dual processor configurations would be expensive, so you get the picture. Without going into great technical detail, currently Prometheus is roughly the same speed as the Sega Genesis, but still 8 bit as far as main CPU goes. 1 Quote Link to comment https://forums.atariage.com/topic/263010-project-prometheus-a-new-colecovision-compatible-console/page/4/#findComment-3729837 Share on other sites More sharing options...
Zonie Posted March 29, 2017 Share Posted March 29, 2017 (edited) Yeah, I get that. too bad they are not exe compatible. It's never easy, huh? I second the comment regarding it should be super game compatible out of the box.

phoenixdownita Posted April 1, 2017 Share Posted April 1, 2017 So a Z80 processor (likely supporting 20Mhz or higher fast clock mode? Like a Z84C0020 http://www.mouser.com/ds/2/450/ps0178-19386.pdf ) .... well given Moon Patrol ran on the Irem M52 that uses a Z80 seems a fitting teaser. When would you be able to reveal a little more on the architecture? CPU? (you kind of already stated you would like to avoid more than one CPU), '80s NOS chipset? etc....

phoenixdownita Posted April 1, 2017 Share Posted April 1, 2017 The eZ80 seems interesting as well He just said that the timing being off is an obstacle to achieve CV back-compat .... even the MSX TurboR based on R800 had a "secondary" Z80 on the MSX-Engine chip to ensure full back compat (the Toshiba chip 9769 https://www.msx.org/wiki/Toshiba_T9769 ) Quote Link to comment https://forums.atariage.com/topic/263010-project-prometheus-a-new-colecovision-compatible-console/page/4/#findComment-3731937 Share on other sites More sharing options...

techeadache Posted April 6, 2017 Share Posted April 6, 2017 Okay clue me in on this one. Project Prometheus is a RC2014, homebrew computer, that reads cartridges instead of floppy disks.
