- Replaced standard MX footprint with spacebar footprint, including stabilizers
- Fixed courtyard on MX footprints in library to avoid collisions
- Added a DIP switch variant with header position closer to pin 1
- moved option DIP switch/header to align header better with edge of PCB.
- Add combined DIP-switch/Jumper footprint to footprint library
- Fix Apple2-encoder and interface-ascii-atmega2560 schematics and PCB to use
new footprint.
- CapsLock, Line Feed LEDs and D33 were wired correctly, but oriented backwards
on PCB relative to Power and OSI ShiftLock LEDs. Fixed so Cathode is always on
the right.
- Marked Anode for all LEDs with (+) symbol.
- 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
- Update all footprints on sol-20 keyboard and aligners
- Add soldermask clearance around cherry MX posts
- Move Cherry MX pads down 1 mil, and Futaba pads up 2 mils
- Adjust Cherry aligner footprints down 1 mil
- Adjust Futaba aligner footprints up 2 mils
- Move mounting slots up 1 mil on Cherry aligner
- Move mounting slots down 1 mil on Futaba aligner
- incorporate improved stabilizer post adapters in futaba aligner
- add slots for stabilizer posts in futaba aligner and Sol kebyoard PCB
- Move stabilizer bar bend guide to left bottom edge to facilitate bending
- Bump rev to 1.6
- 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.
- Slightly narrower posts.
- slightly smaller hole, closer to end
- added mouse bites for breakaway to avoid protruding breakaway
- Applied to Sol and Classic
- 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.
- 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
- 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
- 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.
- adjust RC constants to use simple, common values and reduce number of
different part values.
- Create add-on PCB to provide reset/shiftlock function for older 542 and SB2
keyboards.
