Are there any?

I mean those chipset-specific modes for register-level compatibility with CGA and/or Hercules.
Common in ISA cards, but I haven't seen any PCI card with such a feature.

I think there's a hope with ATI Mach32, as the ISA variant does support that - anybody has a PCI one and can try it?
Anything else?

In 2003, I voted in favour of joining the European Union. However, due to recent developments - especially the restrictions on cash usage - I'm hereby withdrawing my support. DOWN WITH THE EU!

I have a pci mach32 & have tested it with atiutil that changes graphics mode from vga to hgc. Everything works like my old vlb version of mach32.

If that's suffcient, then it might be safe to say there exists a pci card with cga compatibility.

OK, thanks!
Note to self to grab a PCI Mach32 sometime - while it isn't very advanced by PCI standards, the CGA/HGC compatibility option may come in handy.

Meanwhile, I've been testing various PCI cards, and browsing through datasheets - and haven't found anything else...
