Quick follow-up: I found little on the web, but there is a Usenet FAQ
that covers this machine. It sounds interesting enough to get:

1) What is CTOS? CTOS (Convergent Technologies Operating System) is a
character based, multi-processing, preemptive multitasking, true
message-based, microkernal OS. multiuser operating system developed by
Convergent. Convergent was formed in 1979, by a small group of ex-Intel
staff. Convergent Technologies merged with 3COM in 1986. Unisys
purchased Convergent Techonologies in 1986. CTOS is now supplied by BULL
& Unisys. BTOS (Burroughs Terminal Operating System) was a licensed
variant of CTOS.

[...]

   B27: (CM-002) First and only F-Bus model. 80186. Up to 1MB
        memory. Burroughs made these at its Flemington, NJ plant
        under license from Convergent. There is a module which
        allows F-Bus and X-Bus modules to be used with each other.
        Cluster speed is 1.8 Mbps, RS422.
