    45 A bit of history (according to Ulrich Grözinger's excellent memory):  Design and construction at MPIA, start of project ~1981 (as filler project). A very similar copy was build. The copy was originally planned for the [https://de.wikipedia.org/wiki/Gamsberg Gamsberg] in Namibia, partially owned by MPIA, but eventually given away to an association of amateur astronomers. KING was erected in the Eastern dome of the Elsässer lab in May 1986, first light in June 1986, first presentation to the public at the open-house day in July 1986 (ELT designers can only dream of such an implementation speed...).
     45This telescope, built under the directorship of the MPIA's founding director, Prof. Elsässer, was completely designed and manufactured by the in-house Mechanical Design and Construction Group (Mr. Belleman) in the early 1980's. The electronic drive was also constructed by members of the institute.

     50The telescope was initially used for testing and improving astronomical instruments built for the Observatory on Calar Alto (Almería, Spain). The telescope was maintained to be in an operational mode at all the times, though more attention was given to purely mechanical rather than astronomical function. As time went by, the instrumentation being designed and built for Calar Alto  became heavier, and therefore o longer possible to mount these large instruments on the 70 cm telescope.
     51Since then, the 70 cm telescope was mainly used to demonstrate the behavior and work of a professional telescope to visiting groups of for small observational programs of members of the institute.

     53In 2014 a CCD and its control electronics was installed. This upgrade from the more than 20 years old system provided the telescope with a operational CCD with hopefully at least another 20 years to go. This CCD is currently in operation.
     54During 2020 the computer old computer (from 2014) was renovated and the CCD control software migrated to the new computer. 
     55Although the telescope remained operable, it saw less and less use as time went by.
