David Fenyes 97cda49e31 Modifications for multiple keymap support. 
- Added C preprocessor macros to determine largest key matrix, so enough space
  may be allocated

- Cleaned up keymap definition macros for readability

- Created master keymap file to aggregate individual keymaps

- Modified make files to copy the specified master keymap
  to asdf_keymap_defs.h during build.

- Added template keymap file.

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.
