Here is the manual: http://jb-electronics.de/tmp/TR-60S1A-manual.pdf
To add to the mystery, I should say this: I managed to get the display
to work with a composite signal and a GS1881 sync separator to extract
the hsync and vsync pulses. I know that the timing is a bit off, but by
tweaking the v-hold and h-hold potentiometers I goit a stable image, but
it was seriously underscanned (i.e. did only cover a small part of the
screen). So the monitor works well, I believe.

Jens,
The CRT monitor may not be adjusted properly. The horizontal
oscillator probably has a frequency control. This what we called
Horizontal Hold on TV sets.
Do you have any documentation such as a schematic, service manual or
similar for it?

Hey David, I had a few minutes spare time tonight and I verified
that both the hsync and vsync signals appear at exactly the right
frequency (19.2kHz and 60Hz, respectively) and have the correct
duration. Yet, the image is still garbage. How can that be, any ideas?
