- 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
- 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.
- 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.
- Clean up diode positioning and numbering
- Remove 3D models for devices that are not normally fitted
- clean up labeling
- update README files to match PCBs.
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.
- 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.
