5fa0f80b4e Add OSI interface schematic 
Provides a keyboard interface to interface with OSI computers.  Equivalent to an
OSI 542C.

- Includes sound circuits

- Includes RESET delay circuit

- SHIFT LOCK can be mechanical push-on/push-off or soft toggle, selectable by
jumper.

- Provide SHIFT LOCK LED output.

e784abe263 Moved mounting slots from keyboard PCB to aligners 
- This allows the PCB to sink below the mounting brackets.  The aligner height can
be adjusted relative to the mounting brackets using spacers.

- changed futaba aligners to use cherry stabilizers.

- bumped rev number

89bfdd71a9 Move LED current limit resistors to keyboard PCB 
For better matching of current limit resistors to LEDs, the resistors are moved
to the keyboard matrix PCB, where they can be tuned for maximum brightness (at
100% duty cycle).  This allows consistent keyboard brightness when a single
interface PCB is swapped between keyboard matrices.

58126667d9 Add a header-and-mounting-holes footprint with fewer mounting holes 
The SOL-20 keyboard doesn't have space for mounting holes right next to the
matrix header, so the new footprint eliminates those mounting holes.

6e21b96519 SOL keyboard adjustments 
- Fixed position offset error in first three rows of the SOL keyboard

- moved key matrix interface connector to bottom of board so the parallel output
connector can be at the top of the keyboard.

- Adjusted size of mounting slots to accommodate #6 screws.

- ongoing clean up of traces.

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.
