Minutiae:

Can be used only with the Quadra 610 or Centris 610.

Motherboard memory can be shared between the MacOS and the DOS Compatibility card, or the card can accept a single 32 bit wide 72-pin SIMM for maximum DOS/Windows performance.  Use of a dedicated SIMM leaves all Mac motherboard memory available for use with Macintosh software.  

32 MB and 64 MB SIMMs work only with software v 1.0 and PC Card SIMM Patch or with software version 1.5.
