TCE-160
Mixer cipher machine - wanted item

The TCE-160 was an online/offline cipher machine for telegraphy signals (telex), developed by Standard Telefon og Kabelfabrik A/S (STK) in Norway in 1963. It is the transistorized version of the earlier valve-based ETCRRM (1955). The mechanical construction shows great resemblance to the SELMA OKA-150 OTT-machine of 1960. These types of machines are known as mixers.
 
The key tape reel is mounted at the rear left and fed through a paper tape reader at the front left. The image on the right shows a typical TCE-160 with a single Creed paper tape reader on its top surface. The image clearly shows that provisions are present for a second tape reader, allowing the machine to be used off-line.

For the generation of suitable random key-tapes, STK had developed the special KTP-3 key-tape production machine.

If you have any further information about this machine, please contact us.
