Mixer cipher machine
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) and shows great resemblance
to the SELMA OKA-150 (1960).
All these machines are so-called 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,
