The Last CDC Cyber 180/960 Mainframes, a 39-year era comes to an end

The colleagues in Vandenberg (USA) have shut down their 960 forever in June 2021.

I really hope we get our 960 back in service. At the moment it doesn’t look bad, our small data center doesn’t have a suitable power connection. However, the new building is almost finished, only small things are missing.

Cray YMP-EL start up after VCFe 2018

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

Power for the Cray
Power connection to cab two
IPI wiring cab2 to cab1
IO System connectors interchange
Load IOS
Unicos up and running

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.

IBM 360-65 and 360-44 Operator Consoles

IBM 360 consoles, 360-65 & 360-44

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”.

Vintage Computer Festival Europe 20.0

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

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.

Cyber 960 first run without any errors

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.

Disassembled fan, bearings

Fan housing with field coils

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.
