AtariNostalgia Posted June 27, 2021 Share Posted June 27, 2021 I'm struggling to get color out of my IIc. I found this at RM. Would it give a color output? Anyone test one of these? Thanks. https://www.reactivemicro.com/product/reactivemicro-mini-av2hdmi-video-adapter/ Quote Link to comment Share on other sites More sharing options...
trash_44fr Posted June 27, 2021 Share Posted June 27, 2021 Since it is using the composite output which is balck & white only on a PAL machine, I don't think so. As far as I know, the only options to get color output from an Apple IIc will be using the official Apple //c "Chat mauve" scart adapter (search for "Le Chat Mauve //c RVB PERITEL Apple") or the VGA converter from Plamen.

AtariNostalgia Posted June 27, 2021 Author Share Posted June 27, 2021 there is a cable that comes out of the rgb port and delivers 2 composite leads. Would that work? On the NTSC machines, it works like a normal composite video signals. I attached a photo Quote Link to comment Share on other sites More sharing options...
cybernesto Posted June 28, 2021 Share Posted June 28, 2021 No, that wouldn’t work either. It only picks the composite and audio signal from the video connector. There is a separate Apple //c PAL Modulator/ Adapter, Model No. A2M4023 that appears from time to time on eBay that would also produce color, besides the two options mentioned above.

YannAros Posted June 28, 2021 Share Posted June 28, 2021 Did anyone try the schematic available here : https://kaput.retroarchive.org/appleii/ ? I’d like to give it a try but would like a report before. Quote Link to comment Share on other sites More sharing options...
AtariNostalgia Posted June 29, 2021 Author Share Posted June 29, 2021 Does the Pal IIc even have color? I mean does it produce color internally, or is it done by external modulators, boxes, monitors...etc...? Quote Link to comment Share on other sites More sharing options...

AtariNostalgia Posted June 29, 2021 Author Share Posted June 29, 2021 But it works with a color monitor of the era, right? I mean it couldn't have been marketed as a B&W computer?? Quote Link to comment Share on other sites More sharing options...
cybernesto Posted June 29, 2021 Share Posted June 29, 2021 The PAL Apple //c was usually sold with the monochrome 9” monitor. If you wanted to have color, you would buy either the PAL modulator or the Chat Mauve. The same applies to the Apple Europlus. It required a PAL card on slot 7 for color. In Europe Apples were not known for having color. This only changed with the introduction of the IIe. Quote Link to comment Share on other sites More sharing options...

I will try to correct this and post a schematic if I succeed. 1 Quote Link to comment Share on other sites More sharing options...

YannAros Posted July 19, 2021 Share Posted July 19, 2021 Half success! Left : expectation, right : actual output Sync was really one of the issue, but there are further ones creating heavy banding in luminance signal and preventing some transitions to occur correctly. 2 Quote Link to comment Share on other sites More sharing options...

Nice to see a report about this solution working on an apple 2c. It would be very nice if you could explain what you bought/built and how you configured it.

YannAros Posted July 22, 2021 Share Posted July 22, 2021 Looking around it seems that you need this head board for the PI Zero : https://github.com/hoglet67/RGBtoHDMI/wiki/Bill-of-Materials-(12-Bit-Board) However there seem to be no pre-build boards available to purchase anywhere. I'd like to get one, but building it is not very cost effective for one board. Is there anyone offering this? Quote Link to comment Share on other sites More sharing options...
