787e49e1d9 Cleanups, use cherry aligners with futaba keys, bump rev number 2020-04-08 02:03:50 -05:00

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.

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.

dff3830307 ASCII interface update
- Fix wrong direction DIP switch diodes
- Add buffers to permit ISP lines to also be used as output and LED drivers

adcb32aada Swap "O" (Cap O) and "0" (zero) keys
The "0" and "O" keys were swapped on the PCB, requiring a keymap fix for the
ASCII adapter.  The swapped keys would not be an issue for a keyscanning ASCII
converter, but would preclude use in OSI systems, so this fix puts the keys
back in position compatible with OSI.
