Just saw the guy who worked at the place where these two 1974 Telecommanders came from. He admitted he never had time to try them out, just getting two when the opportunity arose long ago, for one future project as we ALL have.
I was impressed by the service info alone, though not fluent in german. So on this visit, I paid a fair sum for his former employer's own 1978 SABA 15" with capacitive touchpad tuning, used as a bedroom set. Pictures coming but it may not have a raster to show
