Last year we mainly took care of the CDC 960. It’s time to continue with the small Cray.







The Cray is running, I am very happy that there was no bigger problem. Now we can take care of the UNICOS and the network.

We got two IBM consoles.
From the IBM 360-65 and the 360-44, the special thing about the 44 is that it is labeled in German.
Thanks Wolfgang Kainz- Huber for the quick reaction and the organization.
In the future we will probably build a 360 emulation with a RaspberryPI to make the consoles “blink”.
Yes, it’s VCFe again! This time we are not represented with an exhibition. But there will be a lecture on Cray-Cyber on Saturday. Generally Saturday, Wolfgang Stief continues his lecture series on Cray with the Cray 3, unconditional recommendation.

Paul Allen died very suddenly seven days ago.
That was very close to me, although I never met Him personally. I followed his projects like the “living computers museum + labs” with interest and respect.
Our member Gerard van der Grinten was personally on site in Seattle to help with the start-up and repair of the CDC 6500.
The world has lost a great man, he has moved so much.
My condolences to Paul Allen’s family and friends.
We are proud to be represented with the Computermuseum München in the 40th anniversary issue of Chip. Over 6 pages you can learn more about us and our Cyber 960. We would like to thank the Chip for making this possible. More of the magazine chip under www.chip.de, at chip-kiosk.de you can buy it.
We does some tests and find one stuck bit in communication between IOU and memory. Measured the communication channel with modern Lecroy scope.
All variable transformers had to be cleaned, now the power supply is stable again. We tested the currents through the transformers and diodes with the clamp ammeter.
A short video @youtube about the Cyber 960, you can hear the 400Hz and the fans.
Fan repair at the console CC545, we disassembled the engine and greased the bearings. Now we know that a second fan is installed, because the first one is now quiet.
The installation of the cables is completed, now we start troubleshooting.
Many thanks to Jerry, he sent us a new IOU to CPU cable.
Our Cyber CC545 console urgently needed thorough cleaning. The picture tube works at 17500V so we don’t take any risks. The housing has also been repaired.
The IOU transformer had contact problems, we disassembled it and cleaned all contacts and surfaces.
The CDC Cyber 960 is alive, we can access the IOU, but the dead start fails.
Stay tuned!
A lot has happened in the last few weeks:
Here are some impressions:
