Working under Tom Kilburn at Manchester University, Richard Grimsdale and Douglas Webb, demonstrated a prototype transistorized computer on November 16, 1953. The 48-bit machine used 92 point-contact transistors and 550 diodes fabricated by STC, the UK arm of ITT.

What was the first transistorized computer?

The TRADIC (for TRAnsistor DIgital Computer or TRansistorized Airborne DIgital Computer) was the first transistorized computer in the USA, completed in 1954. The computer was built by Jean Howard Felker of Bell Labs for the United States Air Force while L.C.

When was the first transistorized computer?

In January of 1954, supported by the military, engineers from Bell Labs built the first computer without vacuum tubes. Known as TRADIC (for TRAnsistorized DIgital Computer), the machine was a mere three cubic feet, a mind-boggling size when compared with the 1000 square feet ENIAC hogged.
