Roger,
I have a Samson Mount made in 1988, am in the middle of fitting it out
with a pair of 9" drives and servo motors controlled by the Sitech system.
See:
www.gototelescopes.com
When am done it will have full GOTO.
As a result I have the original drive and the tanget arm slow motion control for the DEC axis, is this of any use?.
am going to list them for sale in a few months anyway.
regards
Paul Camilleri
