Dave adcb32aada Swap "O" (Cap O) and "0" (zero) keys 
The "0" and "O" keys were swapped on the PCB, requiring a keymap fix for the
ASCII adapter.  The swapped keys would not be an issue for a keyscanning ASCII
converter, but would preclude use in OSI systems, so this fix puts the keys
back in position compatible with OSI.

Unified ASCII Keyboard

This project aims to provide a (near) universal ASCII keyboard for vintage computers. Home computers of the 1970's typically either polled a switch matrix, or interfaced to a parallel ASCII keyboard via a parallel port.

The keyboard allows use of Cherry MX keys, or Futaba MD-4PCS (aka eorge Risk KBM-01-01) keys.

The keyboard is designed using KiCad in order to be the most useful for anybody wishing to modify the keyboard for more specific uses, or to add to the project.

This keyboard project so far consists of:

  • A classic retro-style ASCII keyboard, modeled after the ADM-3A keyboard, which can be also be populated to fit perfectly in an Apple II/II+ case, or an OSI case.
  • A keyscan/decoder interface module that can output parallel ASCII, and can be adapted for other protocols.
  • An OSI-compatible interface module.
