A long time ago, I use to work on a very old analog computer made with tubes. It was 120 separate op amps that had a +-100V swing. Yeah, if you got on that “One” it was very painful.

It’s not the only vacuum tube computer on display in a museum; ... Apropos of this, TNMoC at Bletchley Park also has a replica of EDSAC (construction delayed by the pandemic ...

Enormous dimensions, complicated military calculations, and thousands of vacuum tubes—this was the early supercomputer. HISTORY & CULTURE How supercomputers paved the way for laptops and chatbots ...

Researchers from UC San Diego are using vacuum tube technology to develop more efficient computer processors. The research could result in faster microelectronic devices and better solar panels ...

The room-size computer used 5-foot-long mercury-filled tubes for the main memory. It relied on 3,000 vacuum tubes , arranged on 12 racks containing just over 140 chassis, for computational operations.

The Computer Conservation Society will take three years to create a copy of EDSAC and the build will go ahead in full sight of visitors to the National Museum of Computing at Bletchley. Designed and ...

The National Museum of Computing at Bletchley Park has unveiled its ongoing construction of a replica of Cambridge University's EDSAC computer (1949-58), which helped pioneer novel concepts such ...

Researchers have developed a vacuum tube prototype that is both fast and tough against radiation, making it ideal for computers in space. Researchers have developed a vacuum tube prototype that is ...

EDSAC effort. One of the first ‘modern' computers created by clever chaps at Cambridge University in the late 40s is to be re-built at Bletchley Park. The UK's Computer Conservation Society (CCS ...

Vacuum tube technology is making a comeback, with physicists hoping to use miniature 'vacuum transistors' to make increasingly-smaller computers. The development comes just as the laws of physics are ...

The first recognisably modern computer - the Edsac - is to be rebuilt at the UK's former code-cracking centre Bletchley Park. ... (5 feet) long tubes of mercury used as a memory store.
