The Eco2 layer is used for OSI mounting holes. Adding the eco2 layer to
the OSI mounting holes part allows export of these parts along with the
keyboard cutout as a DXF for case design.
- 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
