Yes.  From the Rocket Read Me file, regarding Mac II's with revision A ROMS:

"Rocket is incompatible with early Macintosh II's that are equipped with
Revision A ROMs.  The Revision A ROMs are only found in Macintosh II
computers manufactured before January 1988.  Please contact your authorized
Apple dealer for upgrade information."

No.  The Rocket runs using whatever ROMs you already have.  If they're 32-bit
clean, then you do 32-bit clean stuff.

Yes and No.  Programs like Maxima, Virtual, and/or Optima should shortly be
Rocket-compatible.  Contact Connectix for more information.
