Hi Jules,

Intel 310 systems were pretty common.  On the RMX side they were used for 
industrial control and automation.  On the Xenix side they were business 
systems used in transaction processing and distributed computing systems.

A company called InBus purchased all of the rights for Intel's development 
and MBI/II systems and O/S's.
