ed5f3fc8d6 Moved Cherry MX and futaba pads farther apart in combined footprint
- Offset cherry MX pads and aligners downward 0.004" from origin

- Offset futaba pads and aligners upward -0.004" from origin

- Update footprints in classic and sol-20 pcbs and aligners

- adjust mounting slots in Sol-20 aligners to match futaba or cherry offset

c13672b408 Multiple fixes for keyboard PCB
- in combined CherryMX/futaba footprints, moved cherry pads down 1 mil and
futaba pads up 2 mil, to reduce risk of shortin of LED pads with futaba pad.
Adjusted all aligners accordingly

- Fixed centroid for combined diode footprint and adjusted PCB placement on
classic and SOL keyboards accordingly.

- Moved SMT pads in combined diode footprint to top layer, so pick & place file
will be usable.

- changes to futaba stabilizer design.  Longer post adapter passes through slots
in keyboard and aligner.

- Changed futaba post thickness gauge from board outline to a slot to improve
tolerance.

- Moved spacebar stabilizer bending guide to edge of PCB, in order to make it
more useful in bending PCBs.

- Changed Apple II mounting slots on classic keyboard from horizontal to
vertical orientation, to accommodate the different spacing offets due to the use
of spacers in angled mounting threads.

14248df6fe mechanical fit and buildability fixes
- Moved header slightly forward

- Moved interface mount holes do reduce interference with case mount holes

- For all keys in classic keyboard, add option for either through-hole or SMT
diodes and resistors.

0ddc216f13 Fixes for classic keyboard outline and mounting hole patters
- Adjust upper right corner circular cutout for AppleII+ case fit.

- Adjust OSI mounting hole pattern for improved fit.

- Changed OSI mount holes along top of keyboard to slots, to fit both C2P (542
keyboard) and C4P (542 Rev B/c keyboards).

- PCB and aligners must be slightly taller to accommodate the slots along the
top row

fb28dd34fc Multiple fixes to classic keyboard for fit and build ease
- remove material from PCB to allow keyboard to fit in Apple II case

- enlarge center hole on cherry MX footprints slightly, to 0.160" to allow
slightly more tolerance, which eases assembly.

- include holes for LEDs on futaba aligner

- include extra pads on main PCB for LEDs with futaba keys

- Add LED on LINE FEED which maps to REPEAT/CAPSLOCK on Apple II keymap

a3a015a759 Update Sol keyboard to 1.5 (Minor changes)
- Fix title in Schematic

- Slightly enlarge center post hole on switch footprint, to allow a bit of
tolerance. Very tight tolerance makes the keyboards hard to assemble.

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.

a03a207a09 Keyboard layout updates
- Add extra key to the left side of row 4 to permit "inverted T" for those who
  want it.

- Tiny shifts of several keys to correct key distances

- Include mounting holes with daughter board connector, to ensure consistency.
