The service manual with specifications is here.įirst, you might be able to put your VGA adapter into a mode whose timings are compatible with MDA without releasing any magic smoke. The cable shown in your photo ends in a DE-9 plug which is standard for MDA, CGA, and EGA. The monitor shown is a Philips BM7523 which is a 12 inch amber monochrome MDA/Hercules display. *5 - Advanced Graphics Architecture - not to be confused with the later Amiga Chipset of the same name - which got in turn named AA in Germany :)) *4 - You may want to take a look at the German Wiki entry for the PC10, containing a bit more information, as these machines were not only developed at Commodore Braunschweig, but also quite popular as 'high quality' clones.

*3 - While 75BM13 sounds like directly taken form Philip's name for the green version BM7513, Commodore used it (only) for the amber one. *2 - Not to be confused with the 1901 colour monitor, based on a Thomson model, that got sold with C128 and early PC10 (for CGA Mode).

*1 - Legally, going by the FCC ID BOU, by Philips Consumer Lifestyle of Hong Kong. Heck, there are even PCIe to ISA bridges except they are usually a bit expensive. There are a large number of USB to ISA boards, ranging from hobbyist projects to commercial products, offering anywhere between a single slot or 8 slots. Now, widening up a bit why not use either an old PC, or if it has to be the new one, why not add an old graphics card to your new PC? I've tried searching, but so far I've only found solutions for hooking a C64 up with a VGA monitor, which is kind of the opposite of what I'm aiming for.īut that's what the usual way is: using older output generators, like a C64, with modern displays. I bet you would as well not like the loss of information due the downscaling.

The only difference to a standard IBM compatible screen is that a DIN plug is used instead of a DE-9S.Īnyone know how to convert VGA or HDMI to this connector format? While MDA required 720 pixels at a 16.25 MHz pixel clock (video bandwith) Commodore speced the monitor at 800 and 20 MHz.

If you hook up an hdmi monitor briefly just to give yourself a display, you should be able to force the correct resolution onto the adapter in Windows.Īnother thing to look for: what are your PC specs? If you're using Intel iGPU, sometimes it doesn't play nice with those adapters and requires changing resolutions/refresh rates in the Intel console, rather than in Windows' settings.I have this monitor, which I think is a Commodore 64 monitor. So if it was truly passive, it would be a worthless hunk of plastic and wire.Īll that said, these type of devices don't allow EDID passthrough, meaning your system has no idea what resolution your monitor can accept. As you even mentioned, without conversion circuitry, it couldn't possibly work as HDMI does not natively output an analog signal.

I have used adapters like these for years in our work environment as we upgrade PCs, but keep older monitors. It should be noted that even this adapter is "active", it just receives its power from the HDMI port, rather than an external power supply.
