              Philips LTC 2009/51
              Heritage collection CERN-OBJ-CERN-OBJ-IT-115 · Item · 1999

              It was part of a range of high-performance monitors (computers screens) that were associated with other units such as Philip's video surveillance systems, cameras or transmission and control equipment. Included in this range of Philips monitors are LTC 2009 (like this one), LTC 2012, LTC 2017 and LTC 2020 Series monochrome monitors. They offer high-performance images with a resolution of 900 TVL (TV-Lines), or in the case of the LTC 2017 monitor, 700 TVL, making them ideal for remote viewing and video applications. The monitor housing consists of a robust rectangular metal case which minimizes interference from external signals and allows “stacking” of monitors when used in large numbers.

              IBM model M keyboard

              In 1985, the IBM Model M keyboard was created. This timeless classic was a hit. IBM came out with several varients of the model M. They had the space saver 104 key which is the one most seen today and many international versions of that as well. The second type, and rarest is the 122 key model M which has 24 extra keys at the very top, dubbed the “programmers keyboard”. IBM manufactured these keyboards until 1991. The model M features “caps” over the actual keys that can be taken off separately one at a time for cleaning or to replace them with colored keys or keys of another language, that was a very cost effective way of shipping out internationally the keyboards.

              HP 2671G GRAPHICS

              The 2671 was a text-only printer with a maximum print speed of 120 characters per second. The 2671 printers are very robust. For paper, they use normal thermal roll paper sold in most office supply stores for older fax machines. Although thermal printing is a quiet technology, the paper advance mechanism of these printers is plenty loud.

              CERNET Interface Card
              Heritage collection CERN-OBJ-CERN-OBJ-IT-015 · Item · 1978
              Parte de Heritage Collection Test

              Homegrown networking technology pre-dating the internet. This is a CERNnet card developed and built at CERN. There was a lot of space on the card between the components, so the engineers decided to put their portraits on it.

              10BASE5 Ethernet Cable & Vampire Tap
              Heritage collection CERN-OBJ-CERN-OBJ-IT-016 · Item · 1983
              Parte de Heritage Collection Test

              10BASE5 Thick Ethernet Cable, 10Mbit/sec. In the 1980s and early 1990's, Ethernet became more popular and provided a much faster data transmission rate. This cable is one of the first ethernet cables from 1983, a thick, bulky affair. Computers were attached via "Vampire Taps" which were connectors screwed straight through the shielding of the cable.

              CDC 7600 Module
              Heritage collection CERN-OBJ-CERN-OBJ-IT-023 · Item · 1970
              Parte de 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.

              IBM 3705 Communications Controller

              The IBM 3705 Communications Controller is a simple computer which attaches to an IBM System/360 or System/370. Its purpose is to connect communication lines to the mainframe channel. It was a first communications controller of the popular IBM 37xx series.

              8-inch IBM floppy disk

              The 8-inch floppy disk was a magnetic storage disk for the data introduced commercially by IBM in 1971. It was designed by an IBM team as an inexpensive way to load data into the IBM System / 370. Plus it was a read-only bare disk containing 80 KB of data. The first read-write version was introduced in 1972 by Memorex and could contain 175 KB on 50 tracks (with 8 sectors per track). Other improvements have led to various coatings and increased capacities. Finally, it was surpassed by the mini diskette of 5.25 inches introduced in 1976.
