Mouse Controller/ (250-1010) Addendum Faxback Doc. # 5293 Calendar Board Removing the board from the computer may, on occasion, cause the clock battery indicator to go low. If this happens, the CLOCKGET routine warns you that the clock has not been reset since the battery failed. You can clear this condition by using the CLOCKSET routine to reset the date and time. If you attempt to use CLOCKGET or CLOCKSET without the MOUSE.SYS driver, the computer locks up, and you must reboot. Be sure that the MOUSE.SYS program is loaded as described in this manual.
