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.

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.

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.
