ALPS 60% keyboard PCB
=====================
Primary goal is to support 60% cut AEK(Apple Extended Keyboard) layout and fits into Poker X cmpatible cases.
Revisions
---------
Rev.A 2015/03
Rev.B 2015/05 ISO Enter fix
Ideas
-----
### LED ###
Backlight won't support. Indicators may be needed for debug.
LED footprint for ALPS Green?
### PCB mount plate: ###
1.6mm PCB will be OK for switch plate.
SMD LED? WS2812? Matias style underside LED?
### TrackPoint ###
ATMega32u2 has no spare pins for TrackPoint three buttons and signals.
TODO
----
ISP pads:
Support for infinity bottom row: 1.5, 1, 1, 1.5: DONE 03/05
Thumb keys, split space bar: near future
Trackpoint support: mount holes and IO pins: Future revision
Bluetooth support: Future revision
USB connector should be shifted to outside by 0.3-0.5mm. 04/05
ISO Enter Fix:
keycap from Matias doesn't work with Rev.A
https://geekhack.org/index.php?topic=69740.msg1760105#msg1760105
keycap from NEC Rakuraku keyboard doesn't work too
https://geekhack.org/index.php?topic=69740.msg1760805#msg1760805
Matias mount is located at middle of 1.25u while 1.5u on NEC keycap(Alps?).
ISO Enter key position of Rev.A is middle of 1u but such Enter key doesn't exist perhapse.

On their Facebook they said:
we can screw V60 plate on 4 holes of Poker2/Pure Pro case. Basicly , V60 can fit in Poker 2 case. But V60 has 6 dip switch , Poker 2 only has 4 dip switch. If the back side hole space not enough , the plate touch , not balance.
Poker 2 can not fit in V60 case. Because V60 case is a little smaller than Poker 2.
