CELESTA Cubesat mini satellite
Heritage collection CERN-OBJ-CERN-OBJ-DE-120 · Item
Part of Heritage Collection Test

CELESTA (CERN Latch-up Experiment Student Satellite) will be the first CERN-driven microsatellite, developed in collaboration with the University of Montpellier in the framework of a collaboration agreement defined and signed in 2015. The project, supported through the KT Fund, has two main objectives: one is developing and flying a space version of CERN radiation monitor (RadMon) coupled with a latch-up experiment; the second is showing that the space radiation environment of Low Earth Orbit can be reproduced in the CERN High energy AcceleRator Mixed field facility (CHARM). This would open the use for space system qualification activities, and provide a radiation monitor module for future missions.
CDC 7600 module slice
Heritage collection CERN-OBJ-CERN-OBJ-IT-082 · Item
Part of Heritage Collection Test

Each module contained 8 circuit cards for a total of about 300-500 uncovered transistors packaged with face plates so the Freon plates wouldn't touch the circuits. (cooling plates that surrounded each module).
CDC 7600 Module

Part of Heritage Collection Test

The CDC 7600 has been created by Seymour Cray. It was designed to be compatible with the 6600, which allows for a substantial increase in performance. Furthermore the rise of new technologies has enabled this performance by reducing the minor cycle clock period from 100 ns to 27.5 ns (4 time faster). A very large machine, the 7600 had over 120 miles of hand-wired interconnections. It was the most powerful computer of its time. However, this speed caused a ground-loop problem causing intermittent faults, and eventually requiring all modules to be fitted with sheathed rubber bands. The CDC 7600 was replaced in 1983 by CRAY-1A.
CDC 6600 Magnetic Core Memory
CDC 6600 Magnetic Core Memory
Heritage collection CERN-OBJ-CERN-OBJ-IT-020 · Item
Part of Heritage Collection Test

A plan of magnetic core memory with 64x64 bits (4Kb) as used in a CDC 6600. The very first CDC 6600 was delivered to CERN in 1965 and was the fastest supercomputer of its time.
CDC 6600 Cordwood Module
CDC 6600 Cordwood Module
Heritage collection CERN-OBJ-CERN-OBJ-IT-024 · Item · 1964
Part of Heritage Collection Test

The CDC 6600 cordwood module containing 64 silicon transistors. The module was mounted between two plates that were cooled conductive by a refrigeration unit via the front panel. The construction of this module uses the cord method, so called because the resistors seem to be stacked like cord between the two circuit boards in order to obtain a high density. The 6600 model contained nearly 6,000 such modules.
