Dave f0772180cb Break out keymap definitions 
- Separate the "asdf_keymaps.h" files into
-- "asdf_keymaps.h" which is not keymap dependent and contains keymap function
   prototypes
-- "asdf_keymap_defs.h" which contains the keymap definitions
-- Move definitions of number of rows and columns from asdf.h to keymaps_defs.h.
-- keymap_defs.h is copied from the keymaps directory depending on which keymap
   is specified in the Makefile.
-- Makefile fixes for the above changes
-- Fix includes in several files to reflect the above changes.

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.
