[GreenKeys] Infotech M600 + M610 documentation

[shadoooo]

Hello all,
I just acquired an old Kleinschmidt teletype and an Infotech M600
demodulator, including the eye scope M610.
I found useful documentation about the teletype, however I can't find any
detailed information about the M600?
Maybe somebody in this list has the device and could give me some info?
Or even better a PDF of the manual?

Thanks
Andrea
