The reverse was also true; I worked for a company back in the 1990's that provided third part SPARC solutions - probably the only company in the Southern Hemisphere at the time that did so.
One of the more interesting products we resold were the ROSS Technology "Sparcplugs" - you basically had a SPARC motherboard and CPU that fit into a couple of 5.25" drive bays on a host PC. So almost the reverse of the SunPCI cards.
