The BiiN system had an OS written in Ada, as well as a number of
other interesting capabilities (fault-tolerance, capability-based
security, etc.).  However, developing the OS, hardware, and other things
was incredibly costly, and the sales didn't ramp up fast enough
to overcome the $$ invested.

Real OS's are time-consuming to create.
