	Don't know about the RA80 (those were in use before I was born
(okay, maybe a slight exaggeration)) but the RA81's are definately 
usable.

	Yes indeedy, its called a KDA-50.  Supports 4 RA style disks
(ra70's, ra81's, ra82's, ra90's).  Its a two board set.  Don't know
how to answer the other part.

	Don't know about the Sun (I think its scsi).  Not directly, you would
either have to run VMS on the 3500 and then get somebody's tcp/ip implementation that
has NFS or run ultrix and then NFS to your DECStation 3100.
