We are currently working on all systems.
The Cyber 930 console has been converted to XT-IDE with 128MB disk on module, the 960 is completely assembled and is currently being repaired.
The 930 has a problem with its batteries and the 5V power supply from CEAG is defective and is being overhauled.
E10k and Cyber 4000 are also moving into the operating range.
Our 960 covered the room with small pieces of sticky foam. Oli and I removed the acoustic foam from the hood. Now we still have to clean the 960 and our room.
Here are some impressions of the work.
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.

Our Cyber 960
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!
