Hex PerTerm boards - Entrex 480/Nixdorf 620

This board is from Slot 17 of the Heinz Nixdorf MuseumsForum's Nixdorf 620 system on display, in Paderborn, Germany.


For reference, the board from Slot 17 of Dominique's System 620 near Brussels, Belgium:

  1. I don't recall the Hex Per Term being a part of the US version of the 600 series or the 500 series.

    1. Thanks for this insight. This is entirely likely, because as of now, the only surviving complete systems are in Europe. One in Belgium, and one at the Nixdorf Museum in Padderborn Germany. I've seen both in person, and they both have Hex Per Term boards. BUT, the only system chassis that I've seen for the pre-Nixdorf models have a slot only for "Scanner", and not any Hex slots like in the Nixdorf 620 systems I saw in Europe. I'll ask you more specifics like this in email. Thanks!
