Has anyone here tried to take the "Houdini I" Quadra 610 DOS card's riser and use it with the Quadra 6100's DOS card? I've found evidence online that it should be compatible, and you'd end up with a 486DX2/66 CPU instead of 486SX/25, and with sound blaster sound card support. I'm not sure, but it might support networking and some other functions better as well.

Just brainstorming new uses for my Quadra 610... Classic MacOS and DOS gaming box would be kinda a nice combo.
