And using a single pulse causes the same bit to operate like an OR gate. Thus, a single piece of hardware can handle various logical operations depending on the input it's given.

Culminating a year-long project, [Usagi Electric] aka [David] has just wrapped up his single-bit vacuum tube computer. It is based on the Motorola MC14500 1-bit industrial controller, but since [Da… ...

In addition, the signal for latching data in the output latches 3-bit LUT5, 3-bit LUT6, and 3-bit LUT12 ÷ 3-bit LUT16 during the parallel data output (Fig. 13, LATCH1 signal).

It can only add single bits at a time and is limited to kilohertz clock speeds, but it is capable of executing the full RISC-V 32-bit instruction set thanks to nearly 6,000 individual transistors.

The work could lead to new hard drives that store data at much greater densities than currently possible. Today’s technologies require 10,000 atoms or more to store a single bit of information.
