If you’re looking for a unique way of heating your workshop this year, you could do worse than build an 8-bit computer with a bunch of 6N3P vacuum tubes. While there are some technical details ...

The architecture starts with the MC14500B 1-bit microcontroller, which was the subject of a previous vacuum tube computer. People found the unusual architecture difficult to understand ...

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 ...

After a brief review of the history of the K2-W vacuum-tube op amp, an LTspice model is used to create its schematic in ...

But BRL heard about the work of John Mauchly at the Moore School. In 1942, he had suggested using vacuum tubes to speed computer calculations. Lieutenant Herman Goldstine of the BRL followed up on ...

While the first computers were mechanical and famously ran on vacuum tubes, there were other schools of thought that brought us a different kind of computer that ran on water. The Russian ...
