The IBM 3000 is an information recorder which was used for data collection. The data were collected by being punched directly onto IBM cards.
Apple introduced the Power Macintosh G3 Blue and White (B & W) on January 5, 1999. The Power Macintosh G3 line stayed in production until August 1999, and was replaced by the Power Macintosh G4, which used the same chassis. The Power Macintosh G3 originally cost between $1599 and $2900 depending on options. The three original Power Macintosh G3 models shipped with a 300 MHz, 350 MHz, or 400 MHz PowerPC 750 (G3) processor. Just pull on the small round handle on the side of the tower, and the entire side of the computer opens up. The G3's motherboard is mounted on that surface, giving you easy access for upgrading RAM or installed PCI cards. Apple added new ports (USB and the much-anticipated FireWire) that took the place of historic, and quickly becoming antiquated, Mac serial (printer and modem) ports. The Power Macintosh G3 has two USB (12 Mbps) ports, two FireWire (400 Mbps) ports, one 10/100BaseT Ethernet port, an RJ-11 jack for an optional 56K modem, a sound out and sound in jack, and one ADB (Apple Desktop Bus) port. The maximum RAM for the G3 is 1 GB.
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.
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.
With arrival of CDC 6600 at CERN in January 1965, there came the first half-inch wide 7-tracks tape units with magnetic tapes at recording densities of 200, 556 and 800 bpi (bytes per inch).
Oracle StorageTek T10000T2 cartridge has total capacity of 5 TB. It is actually manufactured by Fuji Film, uses Barium Ferrite (BaFe) particles technology data store, but is also equipped with RFID chip. There is over 1 km of tape inside of the cartridge with 3584 data tracks and it supports over 25000 load/unload cycles. The archival life is estimated to be around 30 years and uncorrected bit error rate is 10-19. CERN however usually migrates data to newer technologies roughly every 5 years in order to keep the footprint under control.
The first website at CERN - and in the world - was dedicated to the World Wide Web project itself and was hosted on Berners-Lee's NeXT computer. The website described the basic features of the web; how to access other people's documents and how to set up your own server. This NeXT machine - the original web server - is still at CERN. As part of the project to restore the first website, in 2013 CERN reinstated the world's first website to its original address.
A modern 2.8TB/s router, the backbone of our internet connectivity. This model was in service at CERN from 2008 until 2012.
These are sample fibre optic cables which are used for networking. Optical fibers are widely used in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. This is useful for somewhere like CERN where magnets with their highly powerful magnetic fields could pose a problem.
