Hi,
Is anyone interested in PCS Cadmus/QU68000 systems? We at Hack42
have no idea what to do with them. We need to downsize and these
take up a significant amount of our space.
See http://dev.ramdyne.nl/IMG_2750.JPG for photograph of the
stack.
If you know other people who are interested in beasts like these,
please pass this information on. -- Andreas
Looks like interesting machinery from a German manufacturer!
There is a short blurb about them on de:wp
(https://de.wikipedia.org/wiki/Cadmus_Workstations) saying the PCS
QU68000 were based on (who'd have guessed...) a 68000 processor on a
QBus (!) while the later models sold under the CADMUS trademark held
68020/030 and, from 1985 on, MIPS RISC processors. They ran MUNIX, a
V7 UNIX derivate, with some quite sophisticated cluster integration
(network boot, "Newcastle connection" common superroot namespace,
networked block devices) enabled by a board called the Intelligent
Communications Controller.
The Heriot-Watt University in Edinburgh had some 68K CADMUS systems,
which included a number of standard QBus boards and yes the OS was
virtually 7th Edition. When I got my 11/23 system (running real
standard 7th edition, and including the original tapes) form them, I had
a play with a CADMUS system. it was quite a nice system, but one
problem was that the quad-high CADMUS boards didn't have the same sort
of stiffeners along the back edge that DEC boards do, so they sagged and
had an occasional tendency to short out.
