This is a Weston AOIP standard battery with its calibration certificate (1956). Inside, the glassware forms an "H". Its name comes from the British physicist Edward Weston. A standard is the materialization of a given quantity whose value is known with great accuracy.

MFM Hard Drive with a capacity of 20 Mb.

Western Digital hard drive.

Silicon wafer with hundreds of Penryn cores (microprocessor). There are around four times as many Prescott chips can be made per wafer than with the previous generation of Northwood-core Pentium 4 processors. It is faster and cheaper.

This is for HIPPI cable connections betzeen 25 Metres and 50 Metres. This repeater was developped at Los Alamos National Laboratories.

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’s a 20 GB uncompressed center-load cartridge used in StorageTek T9840 tape drives. The tape is a Metal Particle (MP) tape suitable for use on all Oracle/Sun/StorageTek 9840 A, B, C and D drives. The 9840 tape has an archival life of 15-30 years.

The Tandberg TDV 2215 terminal was produced by Tandberg Data as a model of the TDV 2200 series terminals, and sold by Norsk Data (ND) as product number ND 242, Display Terminal Tandberg TDV 2215. It can be run in a TDV 2115 compatible mode, or in its native mode. The terminal has eight PUSH-keys, providing (by use of SHIFT) sixteen functions. PUSH, Programmable Utility for String Handling, allows the user (or the host computer) to program often used words or code sequences that can be transitted by pushing the appropriate PUSH-key. The strings associated with PUSH-keys are stored in non-volatile memory and are not lost when power is turned off.

System 7 is a single-user graphical user interface-based operating system for Macintosh computers and was part of the classic Mac OS line of operating systems. It was introduced on May 13, 1991, by Apple Computer. It succeeded System 6, and was the main Macintosh operating system until it was succeeded by Mac OS 8 in 1997. Features added with the System 7 release included virtual memory, personal file sharing, QuickTime, QuickDraw 3D, and an improved user interface. This is the first real major evolution of the Macintosh system, bringing a significant improvement in the user interface, improved stability and many new features such as the ability to use multiple applications at the same time. "System 7" is the last operating system name of the Macintosh that contains the word "system". Macintosh operating systems were later called "Mac OS" (for Macintosh Operating System).
