ME-620
OTT cipher machine (mixer) - wanted item

The ME-620 was an offline cipher machine for teleprinter networks (telex), developed by Mils Elektronik in Mils (Austria) in the mid-1970s. The machine offers unbreakable encryption, using One-Time Tapes (OTT), as well as algorithm-based encryption, using the built-in key generator.

The image on the right shows a typical ME-620 machine. As present, no further information about this device is available.   

Help required
