The Osborne 1 Released by the Osborne Computer Corporation is considered to be the first true portable, full-featured computer intended for a larger audience than companies. It includes all the components required to be a completely useful and operational computer system. Indeed the Osborne 1 was cost $ 1,795which is now $ 4,773. Another attractive point was that it was sold with several software, which, sold separately, cost almost the same price as the machine. However this computer has some disadvantages like its weight (11 kg) or its tiny screen that could display only a little character per lines and sized the average size of a phone screen . Another problem was that the computer was a bit prone to overheating.
Introduced under the name "Verbatim", Latin for "literally", these disks that sized more than 5¼ inches have become almost universal on dedicated word processing systems and personal computers. This format was replaced more slowly by the 3½-inch format, introduced for the first time in 1982. Compared to today, these large format disks stored very little data. In reality, they could only contain a few pages of text.
A helical scan recording drive, with a high-speed rotating head sweeping across the tape every few micrometers. Based on a professional video recording system, modified to be suitable for digital data recording. These are commonly used with large computer systems, typically in conjunction with a robotic tape library.
The 3480 tape format is a magnetic tape data storage format developed by IBM. The cartridge contains a single reel. IBM’s 3480 cartridge tape system sought to replace the traditional reels of magnetic tape in the computer center. Because of their speed, reliability, durability and low media cost, these tapes and tape drives are still in high demand. A hallmark of the genre is transferability. Tapes recorded with one tape drive are generally readable on another drive, even if the tape drives were built by different manufacturers.
The Sun Ultra 5 is a 64-bit personal computer based on the UltraSPARC microprocessor line at a low price. The Ultra 5 has been declined in several variants: thus, some models have a processor with less cache memory to further decrease the price of the computer.
Cartridge used in the SONY DMS-24 automated tape library system installed at CERN in 1995 and still in use by the NA49 experiment. Tape length is 1300 m with 100 GB storage capacity.
Introduced at CERN in 1985. It has a storage capacity of 200 MB
A new generation with a reworked motherboard is launched on 2001 with however the same Graphite box. It also included a processor speed-bump, and brought the DVD-R "SuperDrive" to the mid-level model. The Quicksilver PowerMac was available in three configurations: The 733 MHz model, with 128 MB of RAM, a 40 GB hard drive, and a CD-RW drive, was 1,699 dollars, the 867 MHz configuration, with 128 MB of RAM, a 60 GB hard drive and a DVD-R drive, was 2,499 dollars, and the high-end dual-800 MHz model, with 256 MB of RAM, an 80 GB hard drive and a DVD-R drive, was 3,499 dollars. The 733 MHz model is the first personal computer to have a DVD burner, named SuperDrive at Apple. The design was updated on 2002 with 800 MHz, 933 MHz and dual 1 GHz configurations, becoming the first Mac to reach 1 GHz.
This hard drive has got a capacity of 8,6 Gb.
It has a capacity of 1 Mb.
