Pulse amplifier circuit board used in the DEC PDP-5 computer. The PDP-5 was Digital Equipment Corporation’s first 12-bit computer, introduced in 1963.
IBM SMS card “EDA”. The function of the card is a 12V regulator. Part number: 374546.Pulse amplifier circuit board used in the DEC PDP-5 computer. The PDP-5 was Digital Equipment Corporation’s first 12-bit computer, introduced in 1963.
This series of cards were first used in DEC’s PDP-7, and later in the famous KA10 PDP-10 CPU. This card used silicon transistors and were used for the main logic in the higher-end CPUs.IBM SMS card “EDA”. The function of the card is a 12V regulator. Part number: 374546.Quad Inverter w/ speedup capacitors used in the IBM1620 and IBM1311 Disk. Standard Moodular System (SMS) cards became the building blocks of IBM mainframe computers and peripherals from the late 1950s to the 1970s. The singular nature of each card meant that It took thousands to build a computer.
