 Dear All,

 On February 27th 1999, the Gemini North Observatory on Mauna Kea, Hawaii
 reached the important milestone of Engineering First Light.

 At this time, we were successfully running our hierarchical control system,
 based on EPICS 3.12.2 with our added "Gemini" extensions.
 The control of the telescope is achieved on a command and action-complete
 basis with the top-level Telescope Control System initiating the commands
 to 6 lower-level systems.

 All 7 individual systems are EPICS based and besides the hierarchical nature
 of the overall system, there are many interfaces between the 6 lower-level
 systems.

 In addition to the control system, we have a further EPICS interface to
 our interlock system which is responsible for monitoring the status of
 the many interlock events which can be generated on the telescope.

 During the past year, we have been very busy integrating these systems
 with one-another and with the hardware for the first time. This
 represents the culmination of many years of work on these systems with
 the original design and implementation of each component
 having come from many countries and many groups around the World.

 Our goals for the future are to move to faster PPC based processors, Tornado
 and EPICS 3.13.1.

 On behalf of everyone working for the Gemini Project and those who have worked
 on the many components of the control system, I would like to thank the
 collaboration for the invaluable help and support which has made this
 all possible.

 Best Wishes,

 Andy
