A great little board, was pretty obvious to me (electronic engineer) how to install, to the extent that I didn't look at any documentation until it 'did'nt work properly' (it shows monochrome with vertical lines) It does need the additional RGB to HDMI adaptor, available from the same vendor, which also needs an additonal Pi-Zero board and SD card, and mini HDMI to HDMI. It's entirely my error, and would have bought these together had I read it all fully!! Once put together, with the RGB to HDMI board, and some pretty trivial fiddling with the settings (menu that works in much the same way as a lot of desk top monitor .. two for 'up and down' and one for enter... worked it out pretty quickly... Fantastic, rock solid , pin sharp display on my 40 odd year old vic20 Note .. need to do something for audio, lash something up with the din connector and headphones or PC-type speaker//whatever.. one niggle, and I can see why, doesn't seem to co-operate with my 'Penultimate' cartridge, probably a bus contention as the digitizers sits right on data and address bus on the VIC chip . Will investigate and see-- may yet be a user error!
I have reviewed this in the context of a engineering user, not a 'consumer' in the normal sense. That reflects that the documentation is complete and thorough, but it did not feature an 'out of the box' idiots guide. It took me not very long to pick up the fact that the later releases of the firmware have a 'select profile' in the menu, and could simply find my computer and it worked. I would recommend taking a bit of time to at least overview the documentation, but I did find the menu navigation, while not exactly intuitive, just a few moments .. similar to menu on many monitors. Fantastically stable image. (Vic-20)
Look, not everybody wants to have the absolute "pure" nostalgic experience just to re-live the glory days of the 8-bit era. Not everybody needs the whole kit and kaboodle to have fun again. I don't need the old fragile floppies and slow, decrepit drive. I'm not going to waste time fretting over keeping the internal components period-correct, not when some of the biggest downsides can be eliminated and fixed with modern tech. I certainly don't need to limit myself to the small, old-school CRT tubes anymore, not with this awesome little miracle worker doing its thing inside! My C64 has one of those early VIC-II chips that requires the special snowflake firmware treatment (6567R56A), and wow does it ever make things better! I don't even have the RGBtoHDMI portion of the magic spell yet, but I am in awe of what this thing is doing already!
