* Adds JC65 ps2avrGB keyboard * Adds default keymap * Adds personal keymap * Backlight On/off support Migrated code from the BFake. Functionality only on BL_ON, BL_OFF, BL_TOGG. * Backlighting config adjustment Only 1 level supported. * Personal keymap update BL toggle added and RGB layer updates. * Renamed jc65 ps2avrgb directory Renamed directory for more clarity. * Default keymap and default rules * Personal keymap and personal rules * Group JC65 QMK and PS2 versions Group JC65 QMK and PS2 versions, Split directories, Readme for parent folder. * Default keycaps and personal keymaps re-added Default and personal keymaps re-added. Keymaps, Readme, Rules.mk, and config.h * v32a default keymap rules Default to no. * RGB and Backlight default settings Set to yes. * Rules.mk defaults for personal keymap Rules.mk defaults for personal keymap * Revised keyboard readme make paths Revised. * Path correction * jc65 default folder set set default pcb to qmk version * default rules for v32a set to enable backlight and rgb by default.
