X68000 to USB keyboard protocol converter | |||
========================================= | |||
SHARP X68000 is a hobby computer released in Japan.(1987-93) | |||
http://en.wikipedia.org/wiki/Sharp_X68000 | |||
X68000 keyboard has ALPS linear switches. | |||
- DSETK0016CE01 green linear | |||
- DSETK0023CE03 yellow linear | |||
Hardware | |||
-------- | |||
Target MCU is ATMega32u4 but other USB capable AVR will also work. | |||
You can use PJRC Teensy as dev board. | |||

pin6 REMOTE - | |||
pin7 GND GND | |||
Firmware | |||
-------- | |||
Build: | |||
$ cd x68k_usb | |||
$ make | |||
And load the binary to MCU with your favorite programmer. | |||
If you use Teensy you can load with PJRC Teensy Loader tool. | |||
