There was a Solaris 2.1 x86.  But it was dropped by Sun when they
   released Solaris 2.2 and 2.3 (available only for SPARC, in uppercase,
   platforms).  They recovered the x86 and PowerPC ports in Solaris 2.4.
   It looks like the PowerPC port was definitely dropped in Solaris 2.5.1
   (may 1996).


it wasn't "dropped" after 2.1.  the solaris 2.1/x86 tree was competely
separate from the tree for sparc.  they were more like random linux ports
in this regard.  it was not until solaris 2.4 that they got the tree
merged and were able to release again.  also note that 2.1/x86 came out
only a very short time (weeks) before 2.2/sparc did.


also, luke knows sunos 4, 5 and sparc hardware in general pretty well :-)
