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.

dae4b8d322 Replaced the Virtual out pulse function with long and short pulse 
- Replace V_PULSE with V_PULSE_LONG and V_PULSE_SHORT functions.

- replace the asdf_arch_pulse_delay() with asdf_arch_pulse_delay_short() and
asdf_arch_pulse_delay_long() functions.

- modify keymaps to use long and short pulses.

- long pulse is 50 ms.  Short pulse is 10 us.

- Added localizing prefix to keymap definitions to avoid conflicts.

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.
