Hagelin Data HC-5000 series →
The machine comes in two basic variants: a civil version (HC-5700) and
a military one (HC-5750) that is fully TEMPEST-proof. It consists of a main
unit, a keyboard, a Video Diplay Unit (VDU) and a matrix printer.
Optionally, an external paper tape reader/puncher was available.
The larger units are connected together via optic fibers in order to minimise
the TEMPEST effects.
Cryptographic keys are loaded into the device by means
of the KDD-5000 Key Distribution Device. In addition, a chip card was used
for the structure key (Crypto Ignition Key or CIK).

The main unit is in fact a Siemens T-1285
teleprinter, the successor to the popular
T-1000 range.
It was developed by Siemens in co-operation with
Philips and was also used as the base for the
Philips Aroflex II (sold by
Siemens as the T-1285/CA).
But unlike the Aroflex II, the HC-5700 uses a Hagelin-proprietary
cryptographic module and is therefore not NATO-compatible.
