Nibble re: SBus slot expansion in SPARC systems

This is now an obsolete category, but in the early 1990's there were a lot of manufacturers who made SBus expansion boxes including Sun and Artecon (which later became part of Dot Hill). That's because the early SPARCstations only had 2 to 4 slots which was not nearly enough if you wanted to use them as servers and stuff them with Ethernet or Serial I/O adapter cards.
