What is the ARITH-MATIC S1-AU Mk1?


The S1-AU Mk1 is a fantastic DIY hardware kit designed using 7400 series logic chips that enables you to build a simple 4-bit arithmetic unit to perform binary addition, subtraction, accumulation and comparisons.

Some of the 7400 Logic chips used:

  • 74HC173 registers for temporary data storage
  • 74HC283 full adder for binary calculations
  • 74HC85 comparator for logical comparisons

The ARITH-MATIC S1-AU Mk1 isn’t computer programmable, you need to manually input data through an array of push button switches and the binary operations can be traced through a series of ultra-bright LEDs. The USB cable is only used to deliver power to the unit.

What do you get in the kit?

  • S1-AU Mk1 Mainboard PCB
  • Backplate PCB (with mounting hardware)
  • Electronic Components Kit
  • USB Mini Cable (for power only)
  • Operator's Technical Manual (downloadable .pdf - English language only)

I was fortunate enough to beta test this. It's absolutely glorious to gaze at (it's just above my office desk) and, as a 4̢̗̩̤̩̤͇ͤͣ̿ͯ͂͋̓̄͂͡4̡̢̬͔̠̿͗ͣ̅̅̍͜ year old who's spent 3ͫͤ͊̃҉҉͇̝͈͔͈̹͈6̣͈̻̣̮͇͉̞̭̇͂̃̐ͨ͞͠ years doing computer 'things' it's an excellent reminder of where it all comes from while npm downloads packages for my modern, high-level development life.
