Semiconductors and microprocessors

Semiconductors and microprocessors (from Wikipedia) Computers using vacuum tubes as their electronic elements were in use throughout the 1950s, but by the 1960s had been largely replaced by transistor-based machines, which were smaller, faster, cheaper to produce, required less power, and were more reliable. The first transistorised computer was demonstrated at the University of Manchester [...]

Supercomputer CDC Cyber

CDC Cyber my memo. text from wikipedia. The CDC Cyber range of mainframe-class supercomputers were the primary products of Control Data Corporation (CDC) during the 1970s and 1980s. In their day, they were the computer architecture of choice for scientific and mathematically intensive computing. They were used for modeling fluid flow, material science stress [...]


Cray-2 my memo. text from wikipedia. The Cray-2 was a vector supercomputer made by Cray Research starting in 1985. It was the fastest machine in the world when it was released, replacing Cray’s own X-MP in that spot. The Cray-2 was capable of 1.9 GFLOPS peak performance and was only bumped off of the [...]

Supercomputer ETA10

Supercomputer ETA10 my memo regarding supercomputer. text from wikipedia. The ETA10 was a line of vector supercomputers designed, manufactured, and marketed by ETA Systems, a spin-off division of Control Data Corporation (CDC). The ETA10 was announced in 1986, with the first deliveries made in early 1987. The system was an evolution of the CDC [...]


IBM NORC my memo regarding supercomputer. text from wikipedia. The IBM Naval Ordnance Research Calculator (NORC) was a one-of-a-kind first-generation (vacuum tube) electronic computer built by IBM for the United States Navy’s Bureau of Ordnance. It went into service in December 1954 and was likely the most powerful computer at the time. The Naval [...]


text from wikipedia. CER-10 CER (Serbian: Цифарски Електронски Рачунар – Digital Electronic Computer) model 10 was a vacuum tube , transistor and relays based computer developed at IBK-Vinca and Mihajlo Pupin Institute (Serbia) in 1960 ref.(1),(4)]. This was the first digital computer ever[1] developed in SFRY. CER-10 was designed by prof. dr Tihomir Aleksić[1] and [...]
