      It’s a computer in almost its simplest form.

      There’s almost nothing to it, the circuit diagram is easy to read, you program it literally by flipping a couple of dip switches.

      It’s kind of an experiment for someone wanting to get into retro computer or hardware design.

      That said it’s essentially useless and I would much rather buy a kit from Ben Eater start with a 6502 and make something that can actually run complex programs.

        Even with just one bit and a few switches this seems like the sort of thing Picard could use to send an encoded message to Riker and Data in the future should the need arise.

      Turn an LED on and off apparently.

      ETA to someone setting up an array and running Doom or Linux?

      Fun. It does not much, really. Two instructions (add, jump), parameters either 0 or 1, two instructions in total. It just shows how a computer works in general. All key signals are visible (Clock, Program Counter, Accumulator).

      About as useful as a quantum computer, just way cheaper.

        I teach an electronics class and a barebones version of this is one of the early logic gate labs: an SR latch built using NAND gates. It can set and reset a bit!

          This is the perfect gadget for teaching electronics and logic.

          If I was to teach such a class, I would set up exactly that circuit without telling them what it is, and let the kids find out: “You’ve got three LEDs and four DIP switches. Here you have a circuit diagram of it. What is this thing?”

      AFAIK, they are used as relays.

      From https://en.wikipedia.org/wiki/1-bit_computing#1-bit

      Computers and microcomputers may also be used, but they tend to overcomplicate the task and often require highly trained personnel to develop and maintain the system. A simpler device, designed to operate on inputs and outputs one-at-a-time and configured to resemble a relay system, was introduced. These devices became known to the controls industry as programmable logic controllers (PLC).
