I seriously considered buying a Rocket for one of our IIx's but ending up
buying a new fx instead.  Though it's nice to get another Mac, a major reason
for rejecting the Rocket was that we still wouldn't be able to directly access
lots o' RAM (i.e. >16M) from within our apps because our ROMs were "unclean." 
We've got several other IIx's that would be good candidates for a Rocket if
cleanliness wasn't a problem.  Seems to me that Radius and Connectix should
have a serious pow-wow (if they haven't already) to figure out compatibility
issues ASAP.

Shifting from the Rocket back to the IIx and the II for that matter, does 
anyone know if there are 4Mb SIMMs out there which work in these machines? 
Last  I heard (correct me if I'm wrong, I'm getting this n-th hand), there was
something about those Macs not implementing the test mode of the 4Mb chips 
correctly which ultimately prevented the Macs from booting.
