I am gratified by so much interest in the B2X from non-Unisys
people. It is a wonderful machine with a lot of ahead-of-its-times
innovations. I worked with them since 1979 and had lots of success
marketing it in the Far East. It had the clustering and multi-tasking
long before LAN & OS/2 were even conceived. It had context manager
with windows long before WINDOWS. It had protected memory mode since 1985.
CTOS integrated printer device drivers with Generic Print System (much
like what MS Windows is trying to do now) since 1987. It has an
extensive and comprehensive communications facilities: TCP/IP, X.25,
SNA,Voice, modem server, gateways...
The clustering (LAN) runs on cheap twisted-pairs at 3.68 megabits/sec
nowadays. It allows master/slave and/or peer-to-peer file and device
sharing with a comprehensive security and monitoring function in CTOS.
CTOS can support simultaneous executions of CTOS, MS DOS, WINDOWS applications
in separate contexts - sounds like OS/2, doesn't it.
It even has an AT board called a ClusterCard that makes a PC/AT function
like a CTOS workstation.
Nowadays, a B39, for example supports SCSI devices, SVGA-equivalent
monitors, math coprocessor...
A lot of banks buy CTOS by the hundreds for its versatility and connectivity
to various mainframes. Unfortunately, it is not appreciated by most PC
users. There are over 220,000 CTOS/BTOS worldwide.

Ouch. There are over 1/4 million 80186 based NGEN. I haven't seen any
numbers since then, but I assume that some of them are still in service. I
have no idea what the delivery figures are for 286, 386, 486 boxes.
The total number of 8088 and 8086 boxes is probably low tens of thousands.
Or did you mean CTOS sites? That seems high, but closer than 220k boxes.
