David Fenyes 63e733c18d Moved spare LED from caps-lock to @ (OSI shift LOCK) 
This allows the keymap to determine which LED is used, rather than requiring the
decision to be hardwired in at the time of assembly.  For the OSI keyboard, the
LED could be placed on the SHIFTLOCK key, at the far right LED, or in the
CAPSLOCK position, which is just to the left of the RETURN and not otherwise
populated in the OSI layout.

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 George 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.
