The DEC MINC (a PDP-11 dressed up for Laboratory use) typically came with
an IBV11 card - Qbus GPIB. I have one but I've never programmed anything
for it. Presumably, the MINC manuals have more than enough info to get
a working start under RT-11.

I was told, but cannot verify, that one of our local
newspapers (the Louisville Courier-Journal) had one
of these systems; the guy who gave me a "printout"

various fonts with various additional attributes

a DECsystem-20.

Therein lies the difference, the use of CRC vs ECC, floppies have a
fairly
high soft error rate compared to hard errors so detecting an error and
rereading is the strategy. It is also an economy of design that comes

Some months ago I asked on this group what the Computype Compuedit computer
was. I was told by someone (who is that person, by the way?) that it was the
front-end machine to a photo-typesetter from the early 80's. Does anybody
know where I can find pictures of this thing in operation?

No Your not! it is a lousy oscillator and susceptable to stray and all
manner
of bad things. I've seen them NOT work on very well laid out 4 layer
boards
as well.

Yes it is, I've used it to 1GHZ with great success. While I was sick
last week
I even kluged a 75m phone RX on a 2x4" peice complete with 6kc bandwidth
mechanical filter. Looks kinda poor but works solid.

One more addition:
They were bought by FPS (good ol' Floating Point Systems), in 1988, with the
resulting company being called FPS Computing. The FPS 500-series machines
are actually Celerity 6000-series minisupers. This company was another
company like Convex, Alliant, Sequent, etc.

hello !
someone offered my a Celerity computer from 'GEI Rechnersysteme'.
it is mounted in a 19" rack and has a built in tape drive.
unfortunately they cannot provide me further information.
so I would like to ask you on the classiccmp-list:
- where can I get further information about this machine ?
- what hardware is in it ? [bus, cpu,...]
- what operating systems run on it ?
- should I take it or leave it ?
thanks for help,
Andreas

CELERITY SIGNS MAJOR OEM PACT WITH LEADING EUROPEAN DISTRIBUTOR
SAN DIEGO, March 3, 1986 -- Less than a month after Celerity Computing's
introduction of two new superminicomputer design systems, the company has
signed a $3 million agreement to supply OEM configurations of the systems to
GEI Rechnersysteme GmbH, Aachen, West Germany, a leading European systems
house and distributor of of computer systems.
Under terms of the two-year agreement, Celerity equipment, including its
proprietary 32-bit ACCEL (TM) processor, will be incorporated into systems
GEI manufactures and distributes to end-users in industrial automation,
engineering design and simulation, and communications. GEI sells both
customized and turnkey solutions throughout West Germany and Switzerland to
customers including BMW, Audi, Volkswagen, Porsche, Ford, Philips and the
German government.
"This agreement with GEI represents not only a significant expansion of our
presence into the European market, but also a major third- party endorsement
of the performance and capabilities of our systems in the mechanical
engineering arena," said Stephen Vallender, President of Celerity Computing.
GEI installed more than 400 computer systems in 1985. The company is 50
percent-owned by AEG, which recently was acquired by Daimler- Benz/Mercedes.
"We want to deliver the highest-quality, top-performance computer products
to our customers," said Michael Emrich, President of GEI Rechnersysteme. "We
ran benchmarks with all the players in the supermini and CAD/CAM markets,
and Celerity clearly beat the others in performance and price."
Celerity's UNIX (R) - and reducted instruction set (RISC)-based supermini
design systems are the fastest and most powerful office_ environment systems
in their price class for engineering and scientific applications. The
Celerity C1260, introduced in January, 1986, is a dual-processor system with
a benchmarked throughput of 6.15 million Whetstone instructions per second
(W/MIPS). It is priced at $110,000 for a functional system configuration.
The mid- range C1230, also introduced in January delivers 3.25 W/MIPS for
$75,000. Both are deskside systems, allowing engineers to complete design
tasks and compute-intensive analysis operations without off- loading to more
expensive, remote computers.
Three-year old Celerity Computing delivered its first computer system, the
C1200, in November 1984. The company has installed more than 60 systems in
leading corporations, research centers and universities throughout the
United States. Its supermini design systems provide advanced design and
analysis capabilities to professionals in a variety of fields, including
automotive, manufacturing, aviation and aerospace, molecular modeling,
animation, and research.

From: Debus-David(a)AER.ARAMARK.COM
Greetings All,
I am finally decommissioning my old and trusty 960. I have gutted the
chassis for
of all usable boards. They are all available to anyone interested in spare
parts for
the cost of shipping. One hard to find item is a SCSI bootable CA. There are
numerous FL cards and the usual HP-IB cards. I need to move this quickly due
to
floor space problems. First interested party takes all.
Thanks

Often it's not the breadboard but the crude oscillator circuit that was
used. the basic osc used in theory should never work but crystals are
less deterministic and don't know that. The side effect is hard starting
and a slight offset from the marked frequency.

Different issue.
FYI I breadboard on a peice of cheapo copper clad AKA dead bug or
as the RAH calls it "ugly" construction. Works well and the groundplane
is hard to beat. Either name, you lay the bugs upside down and point
to point wire them (solder, programming language #1). Copper is ground
and everything else aint. Goes together fast and tends to be fast logic
and UHF friendly.
