What is a 24 AC?

The answer to IamSparticus' frame rate woes, on a (NuBus Adapter) stick!

. . . I was mostly trying to get a decent Marathon frame rate out of my SE/30. Even with a 40MHz 68040 my colorboard 264 just can't push enough pixels, even though PDS is (supposedly) much faster than Nubus. I don't think a fast PDS video card option exists, and was hoping a decent radius card on the nubus adapter would help.

Apple Display Card 24AC

Radius PrecisionColor Pro 24AC

I need to post a thread in peripherals about these wonderful LittleRedRadiusPixleRockets sometime in the future. It seems the Radius Version is far superior to the lobotomized Apple version in the current LCD era. Apparently there's a LittleGreenRadiusPixleRocket in olePigeon's collection, but I've never seen one.

IIRC, from my discussions with IIfx, the Radius DeclROM enables 60Hz VGA/XVGA output at all resolutions, while the dumbed down Apple DeclROM tops out at 1024 x 768 x 24 bit @ 60Hz. I think I posted something about this in conquests . . .
