I already know the IIc can not talk to any "M" monitor, but curious if this board could bridge the gap? I bet it will. The output is analog RGB and works with analog arcade, PVM, BVM, TV with RGB input that I have tested so far. The qualifiers are: 15khz horizontal sweep capable Sync (and you may need to combine that or add it to green) Analog RGB. Is that M monitor 15khz capable? If so, this board should work.

I'm a little out of my element confirming since I find conflicting information on this model. According to another poster (re: GS, which is a different animal but shares the same problem as a IIc in that it isn't directly compatible with any Mac-specific monitor): | "The problem is that this just isn't a 15kHz monitor. It is a 35kHz horizontal, 66.7Hz vertical monitor. It is therefore not electronically compatible with the IIgs, despite the connectors being physically compatible." https://tinkerdifferent.com/threads/apple-iigs-rgbtohdmi-apple-macintosh-monitors.110/ Quote Link to comment Share on other sites More sharing options...
potatohead Posted November 6, 2023 Share Posted November 6, 2023 Bummer! That monitor will not work with this board. The sweep frequency requirement is too high. 35 and the board is 15... Quote Link to comment Share on other sites More sharing options...
YannAros Posted November 6, 2023 Author Share Posted November 6, 2023 (edited) Hi, Yes this monitor is clearly not compatible with standard output from an Apple 2 that is 15kHz. The RGB adapter doesn't modify the frequencies and the monitor must still be able to display standard NTSC (or PAL) frequencies : 15kHz horizontal and 60Hz vertical (50Hz for PAL). Regarding building up cards from teh EasyEDA project, the easiest is to create an account and order from JLCPCB. You can also order from any other supplier by generating the gerber files from EasyEDA (file/export/gerber from menu). The gerber should be compatible with any online company expectations. I have some populated PCB left (all surface mounted component in place) Bare PCBs are also available from here https://www.vikingdigital.com/product/apple-iic-to-rgb-rgbs-video-adapter-a2crgb/ For fully mounted part I will need to build it and I will not be able to in the next 2 weeks. This one is looking like this, and is 40€ + shipping: I'm from Europe, shipping to US can be expensive Edited November 6, 2023 by YannAros Quote Link to comment Share on other sites More sharing options...
mike351 Posted November 19, 2023 Share Posted November 19, 2023 @YannAros Does this output composite video too, or just RGB? And are they still available? Quote Link to comment Share on other sites More sharing options...
YannAros Posted November 19, 2023 Author Share Posted November 19, 2023 Only RGB output is available. I have a small number of PCBs left for the 2c version for the 2e I still have around 10. Quote Link to comment Share on other sites More sharing options...

YannAros Posted November 20, 2023 Author Share Posted November 20, 2023 @mike351 Standard shipping to Autralia is 15€, the next option is 30€ with increased tracking and insurance. Which version are you looking for the one for Apple 2c or for Apple 2e? It makes no difference for the shipping costs, the weight is similar. We should switch to PM for the next steps Quote Link to comment Share on other sites More sharing options...

Hi, I've sent you several private messages, if I do not get any answer soon I will transfer the adapter I've kept for you to someone else. This is the last one I have and might not do more.

YannAros Posted April 2 Author Share Posted April 2 I had some slight progress those last days, if everything goes lmike planned I shoudl have 5 or 6 Apple 2c adapters ready by end of the week.

Your OSHW Lab page still includes PCB version 1.0. Edited April 20 by Chrisa850 Quote Link to comment Share on other sites More sharing options...
YannAros Posted April 21 Author Share Posted April 21 (edited) The layout is there also, on OSHW page go right on PCB display, 2/2 is v1.1. Edited April 21 by YannAros Quote Link to comment Share on other sites More sharing options...

YannAros Posted May 6 Author Share Posted May 6 Hi, My stock of IIe cards is running low but I still have a few. For IIc it is OK. I'll PM you 1 Quote Link to comment Share on other sites More sharing options...
