Here is a uuencoded tar file for pc minix 1.5:
	kernel/{clock.c,keyboard.c,console.c,const.h,glo.h}.cdif

The screen blanks after about 5 minutes of keyboard inactivity.
The screen is restored by typing any key.  You can change the
timeout value by modifying DISPLAY_TIMEOUT in kernel/const.h .
Send mail if you have difficulties.
