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.

Digital Equipment Corporation RMO3P is a disk pack data cartridge removed from 1980's VAX-11. It measures 15" wide and 4" high.
The 8mm backup format is a format for storing magnetic tape data used in computer systems, launched by Exabyte Corporation. It is also known as Data8, often abbreviated to D8 and writes D-Eight on some Sony brand media. The company was formed in order to take the 8 mm video format and make it suitable for data storage. They did this by building a mechanism and a reliable data format that used the common 8 mm video tape technology that was available at the time. This was the first form of helical scanning used commercially for data storage. The ribbon was made vertically and has a length of 112 meters. It was designed to withstand heat and high temperatures. It has been introduced in at CERN in 1994.
Physicists coded and recorded their programs through series of holes on punch paper tape or on punched cards. It was popular in the 1970s due to its high throughput speed and low cost, paper tape was one of the original data storage methods for computers. Information was encoded in the distinct pattern of holes punched in the paper; the paper itself was oiled to facilitate being run through the reading mechanism and to prevent tears due to brittleness. Though the paper was cheap, it had low storage capacity (only a few dozen kilobytes per roll) and the machinery involved in punching the holes was quite expensive. Higher capacity alternatives, such as magnetic tape, has get developped.
