David Fenyes 01008af937 Break out physical resource functions into asdf_physical.[ch] 
- Split asdf_virtual.c into asdf_physical.c and asdf_virtual.c, moving the
functions that handle the physical resources to asdf_physical.c

- cleaned up nomenclature to be more consistent and less confusing.

- fixed keymap files and tests to use asdf_physical.c/h and new nomenclature.

- added asdf_physical.c to Makefiles.

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.
