Good luck with that, as far as I'm aware they were never released with any version, but as a separate thing (for testing purposes perhaps?). BBoAH says that it doesn't work despite claims to the contrary in CGX promotional literature. There should be an EGS driver for it too, but it's not part of the standard distribution.
Still worth giving it a shot with retinaemu, it will at least get you slightly higher resolutions at OCS/ECS colour depths, with decent refresh rates. Installers heaven has the disks for it.
