CDC 7600 module slice
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
CDC 7600 Module
CERN-OBJ-IT-023 · Item · 1970
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
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
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.
CDC 3300 Timing Disk
CERN-OBJ-IT-106 · Item
Part of Heritage Collection Test

It's a timing disc from the CDC 3300 computer. This computer was released in 1965. Moreover CDC means Control Data Corporation.
CAVIAR Physics Microcomputer
CERN-OBJ-DE-114 · Item · 1980
Part of Heritage Collection Test

CAVIAR (CAMAC Video Autonomous Read-out), developed about 1980 at CERN in Geneva, was a multi-purpose microcomputer for the interactive development, in-line control and monitoring of experiments in high-energy physics. The CAVIAR machine was used in conjunction with a CAMAC system, consisting of a set of I/O modules assembled in a 19" crate. Some of the CAMAC-modules (for instance, analog-to-digital converters) would directly be connected to measuring devices, while another module would give access to a host (mainframe) computer through a high-speed link. The CAVIAR uses a Motorola 6800 microprocessor with 32 kB of solid-state RAM. In 29 kB EPROM the BAMBI (BASIC-like) interpreter is stored. Using the BAMBI graphics commands, graphs and histograms can be shown on the built-in miniature monitor screen. An alphanumeric terminal is connected to CAVIAR for programming and entering commands. The Super-CAVIAR (shown in the picture) is an enhanced version of CAVIAR with 64 kB RAM, 84 kB EPROM and other improvements.
