Tape reader/puncher - this page is a stub

PEB-61 was a 5-level paper-tape reader/puncher — also known as a translator — introduced in 1963 by Crypto AG (Hagelin). It was used in combination with a BCX/RT-621 device, which in turn was a combination of a CX-52 cipher machine and the optional B-621 keyboard attachment [1].

The device was based on an original idea in 1961 of Boris Hagelin himself, and was designed to make life easier for the cipher clerk. Messages received from a teleprinter link, are first punched to a paper tape in ITA2 format (Baudot). The tape is then fed to the PEB-61 which converts the 5-bit digital code into a 1-of-26 signal (A-Z), which is sent to the B-621 keyboard [1]. This way, the encrypted message is deciphered by the CX-52 and printed directly onto a paper strip.
