If you're speaking of the one from Keyspan, then yes, it should work just fine. The only Apple models it won't work on are the X-Serve and the G5's, and any Powermac older than the 4400 (inclusive) (http://www.keyspan.com/products/sxpro/homepage.2.reqs.spml). And all of the PCI slots in the MDD are 64-bit capable (http:// support.apple.com/specs/powermac/ Power_Mac_G4_Mirrored_Drive_Doors.html). - Tony On 17-May-07, at 5:29 AM, Bruce Ryan Nakamura wrote: > Hello: > > Does anyone know if the SX Pro serial PCI card is compatible with > the G4 > MDD? > > Did I read somewhere that the G4 MDD can only take 32 bit PCI cards? > > Thank you, > > Bruce Ryan Nakamura > > _______________________________________________ > G4 mailing list > G4 at listserver.themacintoshguy.com > http://listserver.themacintoshguy.com/mailman/listinfo/g4 > > Listmom is trying to clean out his closets!
