Sony HVS-2000 "Camera Selector" (luma keyer) service man or schem.needed
 

The Sony HVS-2000 luma keyer has been the subject of a number of projects
over the years, including amateur TV applications (article in CQ some
years ago). Does anyone have available a digitized copy of the service
manual or at least schematic and adjustment descriptions? I am aware
of commercial sources for it but hope that someone has this material
from another project.

Thanks,

Michael
