VGA output on ZXUNO+
Publicado: 26 Feb 2020, 23:40
Hi Folks,
I am trying to build my own VGA output on ZXUNO+ (since there is ony a composite output, and it looks like there several cores that are not working properly with that, such as coleco with a B&W output, vectrex that displays two images etc ...).
I was googling and looking here in this forum to find the ZXUNO+ schematic (especially the expansion connectors and RJ45 connector).
There are many documentations for the original ZXUNO but unfortunately nothing i could get on the newer version.
Using a multimeter i was able to get some of the pinout of the RJ45 connector that can be used to build a SCART cable, such as audio L+R, and also some of the video signals (looking at the outputs of the THS7374), but i am not sure that those signals are actually RGB+Sync or CVBS/Y/P.
Looking at the expansion connector, i was also able to identify some of those signals (since they are both connected the RJ45 connector and the expansion connector), but i prefer to have official documentation / information, since i don't want to mess up my freshly bought ZXUNO+
Any help would be appreciated
Regards,
Zx
