+
+The ARC PDP-10 system will be unavailable for ARC and NIC users
+from Friday, November 17 (6:00 pm PST ) through Sunday, November
+26. (10:00 pm PST). This will give our hardware team a period of
+nine days to work on equipment with a loss of only three SRI
+working days to users (Monday, Tuesday, and Wednesday.)
+
+This is the Network Information Center's notice to its network
+users of the schedule.
+
+ In addition, a login message will be sent starting about 6
+ November to all users showing schedule.
+
+ It will read something like: "THE ARC/NIC PDP-10 SYSTEM
+ WILL BE UNAVAILABLE FOR USE FROM FRIDAY NOV 17 (6:00 pm
+ PST) THRU SUNDAY NOV 26 (10:00 pm PST) FOR MAJOR HARDWARE
+ WORK AS OUTLINED IN (12542,)".
+
+For those who are interested, the hardware facility work to be
+done during this period will include:
+
+ Removal of the Bryant disk, Bryant disk controller and
+ Cybernex drum-disk interference.
+
+ Moving the Tasker display system and DEC dispack (old and
+ new) equipment to their new locations.
+
+ Having Bryant people run a combination drum maintenance and
+ training session to teach ARC people how to change heads and
