I tried making a cable to move the pins around and it did not work on the two remaining displays in my house that have a VGA input. AFAIK, the levels and signaling will not give you a color 80 column display on a VGA input without a signal adapter, so unless you have a 1902, you're kinda screwed, and I just don't have room for that on my desk.

I use one with my 128DCR. I just wish it could accept the screwy almost-EGA output from the 128D. I've never been able to use the 128D in 80 column mode, the adapters for that are pricey for what they do, which would be ok, but no one seems to like the output from them either, so I've never tried. >> >> Justin >> >> On May 8, 2012, at 15:41 , Anders Carlsson wrote: >> >>> Steve Gray wrote: >>> >>>> You could feed the PET's video signal into the green input and simulate the PET display quite nicely I'd guess. >>> >>> Nice idea! I used to own one of those RGB to VGA converters, but as it didn't fit my application (*) I sold it to a friend. Usually when it comes to composite video one has a full colour signal so your approach would not be very useful, but in the PET application it probably would work. >>> >>> (*) I wanted to use it with my Amstrad MegaPC, that outputs a 31 kHz sigal in DOS/PC mode and a 15 kHz signal in Sega Megadrive mode, both from the same 15-pin connector. The boards listed on eBay claim they accept VGA input, but apparently this is false information. When converting from 15 to 31 kHz, the board worked well but when "bypassing" 31 kHz it produced an image that my VGA monitor couldn't sync to - perhaps 62 kHz or something equally stupid? >>> >>> Best regards >>> >>> Anders Carlsson >>> >>> >>> Message was sent through the cbm-hackers mailing list >> >> >> Message was sent through the cbm-hackers mailing list >> > > --------------------------------------------------------------- > |Raymond C.
