- Add extra key to the left side of row 4 to permit "inverted T" for those who
  want it.

- Tiny shifts of several keys to correct key distances

- Include mounting holes with daughter board connector, to ensure consistency.

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.
