The Cray-Cyber Timeline gives a brief overview on milestones we
reached in the past. Find lots of detailed -- mostly technical --
information in our online diary and
our knowledge base

January 2005 up to March 2005
- Defragmenting, defragmenting, defragmenting... lots of boxes,
pallets, transports. Boring but neccesary.
- Power supply of the NEC SX-4 died.
- A Cyber 830 arrived.
- Annual tours day in our server room. This year accompanied by a
journalist from the german Linux Magazin.
- Opportunity to exhibit some logic modules etc. at the german
trade fair Systems in Munich.
- A Cray T3D and a Cray C94 arrived!
- Implemented a RSS feed for our diary.
- Lots of defragmentation at both sites: server rooms and storage
- Ongoing work with installation of a Cray J916 (J90, 16 CPUs).
- Started restauration of a Cray J932 (J90, 32 CPUs).
- Acquired two HIPPI switches, not sure if, when and how those
- Troubles with our central server: kernel upgrades won't always
work as designed.
- Troubles with acquisitions: due to US export restrictions it's not
this easy to get real big iron over to Europe. We startet becoming
experts in US export law.
- Several transfers to our storage site, defragmentation of
storage space: we're awaiting very interesting, big, big iron.
- Defragmentation of our raised floors and user area. That's another
reason, why the NEC SX-4B still isn't online.
- Vintage Computer Festival Europe 5.0. Big success, lots of visitors.
- Improvements on the air conditioning: air hoses arrived and were
- Installed UPS for server and yel.
- Acquired another Cray J916 which will provide us with spare parts.
- Continued restauration work on the water cooling circuits of
the Cyber 860.
- NOS/VE on the Cyber960 now has user management. Finding the
right manual at the right time usually helps a lot :-)
- Ongoing work on the card puncher: hard wired test routines are working.
- Freddy created an
online system log book.
- Partially reconfiguration of our power distribution happend: We've got
an online UPS which is used to improve the 7x24 uptime of the Cray YMP-EL.
- Dual state installation of NOS 803 and NOS/VE 1.6.1 on the
Cyber 960. So far, there is no user management and no network
on the NOS/VE side.
- Cray-Cyber.org has
airplay on a bavarian radio station in their saturday
afternoon radio show.
- Started restauration on the Cray J916.
- Visitors from the HLRS brought one of their NEC techs with them.
He managed to repair our HIPPI problems at the NEC SX-4B.
- Acquisition of two Cray J90 super computers, one donated from
Forschungszentrum Karlsruhe, the other one bought from
- Startet revive of the CDC card punch. First thing is to renew
cables from card punch controller to card punch.
- Repair of the card reader: a tranistor on one of the interface
cards was broken. This was the first electrical problem, so far
all repairs on the Cyber 960 and peripherals were mechanical ones.
Control Data 4680 runs with dual CPU and dual FPU now.
- The CDC 405 high speed card reader is up and running.
second tours day 2003 is a great success. 300 visitors on
one day! Thank you and see you again in November 2004.
- During presentation, the card reader refuses to work. What a
- Two Hewlett-Packard
- Finetuning of card transport at the CDC 405 punched card reader.
Finally, the reader works now.
- Finally, the air condition is up and running. The temperature
is stable at 28 deg. celsius.
- Together with the air con there were several changes in the
infrastructure (add-on fans, some brick walls, etc.)
- We're sponsored by KAMP,
which means we've got a DSL line with fixed IP for no
money. Thank you Kamp.
- NEC SX-4B gets installed.
- Still no air con, still a very hot and dry summer. The max
temperature in the server room is around 55 deg. celsius (131
Control Data 4680 is online!
- NOS/VE installation on the Cyber 960 in dual state mode.
- Bavaria Kälte- und
Klimatechnik GmbH starts work on the air condition.
- Started work on the Cyber 860. First things will be electrical
connections, cooling circuits and mechanical restauration.
- The EMC Symmetrix 3430-18 arrives. The disk array is
equipped with 18GB SCSI disks and provides 1.3 TB capacity in
- Still heavy heat problems, still no air condition running.
- Finally, we have a logo. We also relaunched the web site in a
slightly new design and improved functionality.
- Started work on the NEC SX-4B
Control Data 4680 should be online for quite a while
now. But there are still problems with SCSI-Controllers, CPUs
and compilation of GNU software.
- John built a second interface to connect another IDE disks to
the Cyber 960. This disk is planned for NOS/VE.
- For the first time this year, we ran into heat problems. The
air condition will be weeks away. At least, we managed to get
condenser up and running.
- Installed several ancient worksations in user area.
The NEC SX-4B arrives. Because we are busy with some other work
(preparation for VCFe 4.0, CDC 4680, card reader etc.) there is no
time to immediately switch on the NEC. The machine has to wait for a
couple of weeks...
Finally, the renovation work is completely done. As usual, there
are all the small items at the end, which take most of the time.
During renovation, we had most of the time a running Cyber 960 on
Saturdays and a running Cray YMP-EL 24x7. There were some short
downtimes, usually just for moves or changes in the power
cabling. Overall we are proud of the nice result. White walls, a white
ceiling, cleaned up lightning, a new floor, a nice hand crafted ramp
to the new raised floor etc.
With the renovation, Wolfgang Stief
joined the team and replaces Stefani, who quit some weeks before due
to other priorities.
Great Renovation starts. With the graceful help of
many people it was lot of work but also lot of fun. Now we have raised
floor in both rooms, the Cybers are together in one room, the Unix
machines are together in the other room. We have a user area, some new
power cabling, on the first sight lots of space and a heating
problem. Latter will pop up in summer, we did not yet know about
The Cyber 960 gets a new NOS version. Now, users can connect using
TCP/IP, there is no more need for the serial lines.
Plannings start to reorganize the computer room. There has to be
one more room with raised floor, both Cybers should go into one room,
there should be a user area with ancient workstations, the walls as
well as the ceiling desperately need some new painting. The Great
Renovation is scheduled for February 2003.
On November, 26th, 2003, there is our first Tours Day. We had
around 40 visitors.
End of November 2003, the Cray YMP-EL went
online. First, there were only guest accounts, in the meantime we also
offer personal logins with synchronized passwords on all systems. The
little Cray runs 24x7 (doesn't need this much energy and has fragile
Thanks to Dietl Feinmechanik (Gauting) we could repair our
CDC 580 chain printer: Dietl manufactured a new gear-wheel to replace a
broken one at low cost.
In USA, the Vintage Computing
Festival takes place. Cray-Cyber.org takes part remotely with its
Cyber 960. The Cyber is running 48h for this event.
In September 2002, the Gesellschaft
für historische Rechenanlagen e. V. (GHFR) was founded. The
association has it's main focus on restoring and running ancient
computer systems and preserve related knowledge in forms of
documentation, hardware and software. Cray-Cyber.org is one subproject
960 goes online for public access the first time. Because there
wasn't a TCP/IP-Stack for the Cyber in the beginning, this was done by
16 serial lines. Meanwhile, the Cyber talks of course IP.
Also in August we started reviving some Unix based CDC machines.
The Website www.cray-cyber.org
Software and documentation for the Cray YMP-EL arrives from University
"A small Cray needs an administrator." That's how
Cray-Cyber.org began: During VCFe 3.0, John Zabolitzky
looked for an admin for the Cray YMP-EL. Freddy
Meerwaldt, Alexander Mann and
Stefani Seibold wanted to join John, administering the Cray. In the
beginning, there were monthly meetings on initial planning and
