AVIDAC

The AVIDAC or Argonne Version of the Institute's Digital Automatic Computer, an early computer built by Argonne National Laboratory, was partially based on the IAS architecture developed by John von Neumann. It was built by the Laboratory's Physics Division for $250,000 and began operations on January 28, 1953.

AN/UYK-8

The AN/UYK-8 was a UNIVAC computer. It used the same 30-bit words and instruction set as the AN/USQ-17 and AN/USQ-20 Naval Tactical Data System (NTDS) computers, built with "first generation integrated circuits" which made it about one quarter of the

AN/USQ-20

The AN/USQ-20, or CP-642 or Naval Tactical Data System (NTDS), was designed as a more reliable replacement for the Seymour Cray-designed AN/USQ-17 with the same instruction set. The first batch of 17 computers were delivered to the Navy starting in early

IBM 728

The IBM 728 magnetic tape drive was used on the SAGE AN/FSQ-7 computer. It was physically similar to the IBM 727, but with significantly different specifications

IBM 7330

The IBM 7330 Magnetic Tape Unit was IBM's low cost tape mass storage system through the 1960s. Part of the IBM 7 track family of tape units, it was used mostly on 1400 series computers and the IBM 7040/7044. The 7330 used 1⁄2 inch (12.7 mm) magnetic

IBM 727

The IBM 727 Magnetic Tape Unit was announced for the IBM 701 and IBM 702 on September 25, 1953. It became IBM's standard tape drive for their early vacuum-tube era computer systems. Later vacuum-tube machines and first-generation transistor computers used

IBM 7080

The IBM 7080 was a variable word length BCD transistor computer in the IBM 700/7000 series commercial architecture line, introduced in August 1961, that provided an upgrade path from the vacuum tube IBM 705 computer

Tetrode transistor

A tetrode transistor is any transistor having four active terminals

IBM 738

The IBM 738 was IBM's first core memory unit to use transistorized sense amplifier circuits. Designed in 1955 for the IBM 704, it used vacuum tubes for all other circuits, and provided a capacity of 32768 - 36-bit words. It was also used in the later IBM

Spacistor

The spacistor was a type of transistor developed in the 1950s as an improvement over the point-contact transistor and the later alloy junction transistor. It offered much higher speed than earlier transistors. It became obsolete in the early 1960s with

Disinformation Governance Board

The Disinformation Governance Board (DGB) was an advisory board of the United States Department of Homeland Security (DHS), announced on April 27, 2022. The board's stated function is to protect national security by disseminating guidance to DHS agencies
