I've just written up some recollections about my past experiences with
Reality/Pick. Since it's very quiet here perhaps I may be forgiven the
hubris of daring to think they may be vaguely of interest and I'll
post a link below :-

re:http://en.wikipedia.org/wiki/IBM_6150_RT
from above:
One of the novel aspects of the RT design was the use of a
microkernel. The keyboard, mouse, display, disk drives and network were
all controlled by a microkernel, called Virtual Resource Manager (VRM),
which allowed multiple operating systems to be booted and run at the
same time. One could "hotkey" from one operating system to the next
using the Alt-Tab key combination. Each OS in turn would get possession
of the keyboard, mouse and display. Both AIX version 2 and the Pick
operating system were ported to this microkernel. Pick was unique in
being a unified operating system and database, and ran various
accounting applications. It was popular with retail merchants, and
accounted for about 4,000 units of sales.
