- * Command/Windows key option

- * If you define this, the thumb enter key becomes the Command/Windows key. There's still an enter key on the right

- * DataHands let you remap right ring east as Command, but having it on the thumb is nicer. Comment out this define
- * to use the original layout.

- *
- * In order to get the Teensy to work, we need to move pin 1 to a different pin. This is
- * because on the Teensy pin 1 is ground, but we need to write to pin 1 in order to read
- * the keyboard matrix. An ideal pin to move it to is VPP (pin 31), because this pin tells
- * the 8051 whether it should read from external or internal memory. The Teensy doesn't
- * care about that.
- *
- * The easiest way to reassign the pin is to use standoffs. You can check out this thread:
- * https://geekhack.org/index.php?topic=12212.msg235382#msg235382 for a picture of what
- * this looks like. Note that in the picture the pin has been reassigned to pin 12. We
- * don't want to do that because we're going to use that pin to send data over PS/2.
- *
- * We could if we wanted also reassign the PS/2 pins to Teensy hardware UART pins, but
- * that's more work. Instead we'll just bit-bang PS/2 because it's an old, slow protocol
- * (and because there's already a bit-banged PS/2 host implementation in QMK - we just
- * need to add the device side).
- *
- * So overall, we want the following inputs and outputs:
- * Outputs:
- *   Matrix:
- *     PB7
- *     PD0
- *     PD1
- *     PE6 (moved from pin1, GND)
- *   LEDs:
- *     PB3-6
- *     PF4-7
- * Inputs:
- *   Matrix:
- *     PD2-5
- * I/Os (start up as inputs):
- *   PS/2:
- *     PC1
- *     PE1

-# DataHand
-
-A keyboard designed to prevent RSI. See [Wikipedia](https://en.wikipedia.org/wiki/DataHand) and [this website](http://octopup.org/computer/datahand) for more info.
-
-To use this firmware, you have to replace the stock microcontroller with a Teensy++ 2.0. This is relatively easy and also reversible. See the notes at the bottom of datahand.h for more info.
-
-Keyboard Maintainer: [Nikolaus Wittenstein](https://github.com/adzenith)  
-Hardware Supported: DataHand Personal or Pro II  
-Hardware Availability: No longer in production
-
-Make example for this keyboard (after setting up your build environment):
-
-    make handwired/datahand:default
-
-See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
