Turns out the cheapo AliExpress CGA card I've been using till now was pretty accurate, it has all the same bugs/snow etc. I suppose it's not too surprising, it has the same 6845 chip and that's sort of the most crucial component.

The CPLDs used are sort of interesting. They're still being manufactured and they run at 5v, so ideal for integration into retro hardware. Unfortunately last time I looked the toolchain was a complete nightmare to use. I believe there is an open source workflow now though

@rasteri@mastodon.scot it is kinda amazing to see there is still so much legacy industrial hardware left that it's affordable to manufacture new CGA cards (and how cost effective they are now thanks to CPLDs)
