Working on the CDC960 and reading the backup tape for the CRAY Y-MP EL

A lot has happened in the last few weeks:

  • For the operation of the CDC 960 almost all devices are installed in our computer room.
  • The power distributor is rebuilt and equipped with new fuses, as well as the 400Hz cable from the generator and the 50Hz supply line within our room is laid and connected.
  • The 400Hz generator has been successfully tested.
  • Also from the Cray Y-MP EL there is something pleasing to report, we could read the urgently needed SCAN files from a defective original tape.

Here are some impressions:
