Hi all,
I have found a DEC board called 'CI START COUPLER'. There are two
numbers
on it, 5414216 and 5014215C.
Were was/is it used for and is anybody interested in it (postage only).

A Star Coupler is used to cluster VAXen together, to create a big, uberVAX.
They could share peripherials and, more importanly, disk storage. Unless you
have a bunch of VAXes, and I don't mean MicroVAX, it's mostly useless.

A Star Coupler is a passive interconnect for systems using CI (Cluster
Inconnect). It
is used by VAXen and Alpha based systems to form Clusters which can share
various
things.
I understand (and hope to be corrected by posting here) that the CI
technology was
originally developed as a method of sharing storage for DECSYSTEM-20 systems.

Didn't realise it was that early, but it's certainly been around a while,
and the hardware went through
considerable evolution. The circa 1984 Vax 8530 here has a second 5'
cabinet, which contains a box 19" wide, 12" high and about 12" deep full
of
boards that is the CIBCI? CIBCA?. Equivalent thing in my Vax 6430 is two BI
cards.
I still have a couple of HSC50's and a Star Coupler at home, and we use a
HSC70 and another one
at work on the Vax 6440.
Asides:
Still looking for the Vax Console (Pro380) to 8530 cables so I can try and
get the 8530 running again.
I have the console and reinstalled all the stuff on it, just need the
cables, then I will have to try and mod the 8530 psu
to work on 240v single phase if possible.
If anyone out there has info on converting a Vax 7000 to single phase ops
(US single phase initially) I'd be interested to hear from them as a US
based acquaintance has one he wishes to play with.

A quick google search gives:
http://www.linique.com/dlm/tenex/acmcfs89.txt
which confirms that CI was used to provide a common file system for
DECSYSTEM-20s.

New subject: Before I Ebay....
Sorry to spam a for sale, but I wanted to offer this to the group before
Ebaying....
Times are getting a little tight, so I have to part with some non-Atari
items, so I am making my Corvus Concept 68000 based computer available for
sale.
The system is in excellent cosmetic shape, comes with main unit, Coruvs
keyboard and special Landscape/Potrait Monitor. System is perfect
operational shape and does attempt to boot up, but requires an Omninet Hard
Drive with the Corvus OS installed onto it. The full Corvus manual is on
Al Kossow's site for reference.
If someone is really into exotic hardware, then this is a must have system,
very few Concepts were made and very few are in the hands of collectors...
Okay, enough with the cheesy sales-pitch, Email me if interested.

To help Curt along with this sale, the Corvus Concept is a quasi-GUI
machine in that it is all graphics and window based but the extent of the
windowing is just to parition the screen for a text-based application,
although of course there are applications that take advantage of the
graphics. The windows do overlap as well.
One of the coolest aspects is the system bus: it is kind of a "superset"
of the Apple ][ bus. The edge connectors are the same and the signals are
very similar. Frank McConnell can add more to or correct what I am saying
here as he knows a bit more about it.
The Concept is definitely one of coolest of the early 68000-based
workstations. It is contemporaneous with the Apple Lisa having been
marketed in the 1982 timeframe. It had a very innovative architecture.
A must have. Bid high! :)
