SEECHECK from REDIFON developed with Entrex


The connection comes from this page:

Seecheck (1972)
The technology for the Seecheck system was developed with the Entrex company in the US, Redifon having the rights to sell it in the UK, and also developed a market in Eastern Europe and the Middle East. It was based around the Nova 16-bit mini computer produced by Data General, and set the basic architecture of all the systems developed down to the 2885 in 1990.

Seecheck Basic Control Groups (BCG) used a ‘Lowboy’ rack containing a 17 slot ‘DCC’ mini, tape drive, disk drives and necessary power supplies. The DCC mini computer had a 1200ns processor and 64KB of core store, and was also the only Nova based system supplied with programmers switches built in to the front panel, all subsequent systems having a detachable one for engineers’ use only.


I think the interesting part is this:

In 1974 Redifon signed a licensing agreement with Metronex/Meramat in Poland whereby Seecheck would be manufactured in Poland using Soviet-bloc hardware for sale in Soviet-bloc countries. Although peripherals were available in the Soviet-bloc there was not a suitable CPU so Redifon designed and developed a DG Nova compatible mini, called the P.1, for manufacture in Poland. This CPU complied with the then CoCom strategic embargo. Later Redifon would up-grade this design for the E.17 mini made in the UK.

So that would be a clone of a clone of a clone perhaps

And then somehow we get to this image, which shows the newer Entrex keystation terminal?
