PEB-61
Tape reader/puncher - this page is a stub

PEB-61 was a reader/puncher for 5-level ITA-2 paper tape, also known as a translator, developed by Crypto AG (Hagelin) in 1963. 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.

The device was based on an original idea of 1961 by 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 digital code into a 1-of-26 signal, which is send to the B-621 keyboard. This way, the encrypted message is deciphered by the CX-52 and printed directly onto its paper strip printer [1].
