I think you can use a generic 4164B like this one:

Oww, but both my Color64 and the MX-1600 were modified to have composite video output on NTSC. I changed the cristal oscilator for the NTSC one and removed all transcodification circuitry that existed on PAL-M. Normally, PAL-M Cocos have artifacting yes but a combination of green and blue, instead ...

Besides that, the remaining brazilian clones to be dumped would be the following: CP400 Color II (Brazil) Varixx VC50 (Brazil) Codimex CD6809 (Brazil) Keep up the good work! Edit:Sent the current Brazilian clones roms to MESS ;) Robcfg, I think there is no difference on the CP400-I to CP400-II in t...

I confirmed with the friends of the brazilian coco list that CP 400 models I and II, both used two 2764 EPROMS.

Using PAL-M as you do, do you get the same sort of artifacted colours as NTSC? The colour subcarrier looks like it's *very* close... I want to add a "-tv-type pal-m" option to XRoar, and wonder whether that should default to NTSC-style artifacting (ie be treated identically) or not (turn off artifa...

I only know another person who has this machine and it have keyboard problems. Is there any chance of getting a ROM dump from that machine (temporarily put the EPROM chip in your MX1600) so we can check to make sure that the ROM code from yours has not been hacked and rewritten to the EPROM by a th...

Daniel, I'd need you to tell me for the three systems (Color64, CP400 and MX-1600), which kind of eprom type and how many they have. I see in your pictures that the MX-1600 has only one 16kb eprom, so from MESS viewpoint, its rom files should be in a single file. Again, thank you very much! Sorry, ...

Excellent work, Daniel! Do I have your blessing for uploading your rom dump to the people of MESS? It's one of the systems for which they don't have the roms yet. Regards, Rob Sure!! That was the idea! We need to preserve that stuff, because sometimes is very difficult to find a working machine to ...

Yes, It's exactly a freezing switch.

I think there is an article on the Rainbow Magazine explaining how to add a pause button on a normal Coco.

Hello, Last week I aquired another rare brazilian coco clone, the Dynacom MX-1600: https://lh3.googleusercontent.com/-dt3dfGlWh3k/UQWP3ihXcQI/AAAAAAAACKw/G25EXS4cvRg/s800/IMG_3988.JPG It came on bad shape and not working, but after some work, it's fully functional again. It has several improvements ...
