Nixdorf 620 System in Bremen, Germany - Acquired & Saved!

We were thrilled to acquire this and take delivery!  Now we just need to find a way to get it from it's holding place in The Netherlands to the central USA...we're working on that, and we have great friends in Europe to help!

Nixdorf (Entrex) "Trapezoid" 06418 Terminal saved in Austin, Tx!

This and other vintage machines were acquired by "SomeComputerGuy", from another guy clearing out a storage unit. 

"He does salvage and this is some stuff he had set aside.  I asked him repeatedly if he knew anything about where any of it came from, he did not."

We celebrate SomeComputerGuy's find, and are collaborating to reverse-engineer the terminal communication protocols!  Thanks for sharing the experience with us!

Entrex has been added to Bitsavers!

Many thanks to Al Kossow and team for scanning and making available their full collection of Entrex publications.  Very rare and unknown, mostly, until now!

Here's the collection:

Also Nixdorf has had a collection there since May 2019.

Of particular interest to us here:

Nixdorf 620 Terminals spotted on reddit...

January 23, 2022

So, does NoResponsibility3745 own them?  Do they intend to preserve them?  Sell them?  What is the status?  Well, since Jan 23, NoResponsibility3745 has been silent, so we may never know.  I have sent NoResponsibility3745 a direct message, as well as left a reply in the reddit post thread.  

Hopefully we will hear an update someday soon, and these terminals can be preserved and/or restored.  And maybe even reunited with one of our restored systems to run their proprietary communication once again!

The MERA-ELZAB 7951 Terminal for the Polish "SEECHECK" system - Copy of the Entrex 480

The MERA-ELZAB 7951 Terminal...why does it resemble an Entrex Data/Scope so closely?

And yet, is not the same?

But even the keyboard layout and key labels match the "full keyboard" layout terminals in our collection.

Image samples below, with their sources hyperlinked under each image:

One noteworthy comment on this flicker photo reads (translated from Polish):

Please post where this Mera terminal is located and what it was used for, I'm guessing along with the Mera 9150? For data entry into a larger system?

I replied on April 9, 2022 with my vote of support, info directing to pages on this website, including this very page.
Excellent effort.  We would love to see some updates soon!
Only one suggestion, to make the upper right "HELP!" button black instead of read to match the original terminals.

Good morning,

The items sold in the recent JCPenney auction were items collected and stored in the JCPenney Archives in Plano, TX. As far as we know, all of the items had a connection to JCPenney's in some form or fashion but we have no additional information for this piece. Good luck in your search for information!

Hello.  I'm a vintage computer historian enthusiast, doing some historical research on this item sold at your auction last month:

Can you share any details about its origin?  It's in an auction of JC Penny stuff, but is there a backstory?  Was there a JC Penny warehouse somewhere that this was stored in, along with many other store historical memorabilia in your auction?  Or could some of these items, such as this, be from other sources, just mixed in to this auction event?

Anything you are able to share is highly appreciated, no matter how small.

Best always,

Entrex 480 in Frenchtown NJ

In July of 2020, the attention of several enthusiasts in the Vintage Computing & Restoration space was drawn to this auction of an abandoned storage facility in Frenchtown, New Jersey.

I was certainly among them.  Why?  Well, the Entrex 480 shown in this auction listing.  The fact that this entire website is all about this system quite demanded it come to my attention, actually.

Well, long story short, yes, I acquired the Entrex 480 lot.  

AND the corresponding Sweda 750 lot, shown below...

Terminal Nixdorf

On (Germany!  Again!).  Shipping ONLY to Germany, so of course, those of us in the USA wouldn't see this...

Auction Archive            Bid History Archive

History from the seller, auto-translated from German:

Hello, good evening. My home is currently being renovated, so I can hardly get to the computer ... It took a while.
The terminal belonged to the Biberach District Office in 88400 Biberach. It was used there and at some point stored in the warehouse, I don't know more about it. There are no other parts from this series - I'm sorry.
The IT department there will move and the old building will be demolished, in the course of which the terminal would have been thrown away - an unforgivable mistake. I myself collected computers for a while, from the 80s (CBM 8032 and so on), so I knew that something like this shouldn't happen and I sold it on ebay on behalf of the district administration.
M. Mensing

Well, we got it.  Well, more like we secured it so far.  And yes, we paid too much money.  But we'll get to that later...

Core Memory "Modern" Replacement (for Data General Nova, DCC D-116, Etc)

WARNING:  The below memory card will work ONLY in the "Classic" Nova, but not in Nova 1200 or newer models.

Upon one of my several visits to the Living Computer Museum in Seattle (back in 2019, before they closed permanently because of COVID...), I became quite fascinated with the "not-so-core" memory board in their Data General Nova on display.
