# kc60se
* Keyboard Maintainer: [Blake C. Lewis](https://github.com/BlakeCLewis), [MechMerlin](https://www.github.com/mechmerlin)
* Hardware Supported: KC60SE
* Hardware Availability: PCB is no longer available
## Description:
* 60% keyboard PCB;
* supports ANSI, ISO, and HHKB layouts.
### Enter the Bootloader
* As delivered, BOOTMAGIC_ENABLE = yes:
* unplug keyboard;
* while holding down 'Space' 'B', plug in USB cable and continue to hold for 8 seconds;
* 'lsusb' should report 'Atmel Corp. atmega32u4 DFU bootloader' instead of 'feed 6060';
* in bootloader LEDs are off & keyboard does not work.
* New firmware, BOOTMAGIC_ENABLE = lite:
* holding down esc while pluging in usb.
* Hardware way:
* momentary jump pads 5 & 6 to enter bootloader;
### Compile the default keymap:
make kc60se: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).
### NKRO
* N or 6 Key Rollover NKRO/6KRO
* navigating bios of computer may require 6KRO
* default keymap has fn(T) mapped to toggle NKRO/6KRO
* test: press 8 keys at same time, if 6, then 6KRO, if 8, then NKRO
### DIP switches enable/disable GUI keys, the second keys from the ends on the bottom row:
* K41/K4C are WIN/GUI and will disrupt games;
* Add keycodes GUI_ON and GUI_OFF to your function layer to switch on/off GUI keys. It is eaier than flipping the dip switches;
```
