14" Magnetic Plate * Hard Disk Drive Platter Nixdorf Computer * VINTAGE * Rarity

The original eBay title in German is:

14" Magnetplatte • Hard Disk Drive Platter Nixdorf Computer • Vintage • Rarität

So, what does this disk have on it? Could it be Entrex system OS of information? What does that handwritten label say, exactly? I see that it is similar to the disk packs that Dominique has on his system, which are taken by the Diablo Model 40 disk drive.

Nixdorf Dumb Terminal 1970's and 1979 Nixdorf modem (Bray, Wicklow, Ireland)

From adverts.ie - nixdorf-dumb-terminal-1970-s-and-1979-nixdorf-modem

(I've archived the page here, in case it disappears.)

My closer photo analysis leads me to believe that this is indeed

one and the same terminal that I featured on this site over a year ago

which means that the person who posted this ad 3 years ago is likely the one who bought it from Matteo on eBay in 2008-2009

Description

Hi,

I'm selling my beloved Nixdorf Terminal and modem. The terminal came all the way from Italy - Rome to be precise - where it was found in a Barn! I've owned it for 7 years. It cost around €110 alone to ship at the time!

It powers on and the fan kicks up, but the display is garbled. Who knows, it may be a loose connection somewhere or a chip issue. Not bad given it's age and history I guess! It's time to pass this on to someone who can investigate it further. As is, it's a fascinating slice of history being as it is over 40 years old.

The Modem came from the U.S., and was bought around the same time. It was manufactured in 1979. These are unique items that I'm selling reasonably priced as I'd like the space they're taking up. Needless to say, these are for collection, Bray area.

Thanks for looking!

---------------------------------------------------------------------
I am hoping that we can find the seller of this, since the ad was withdrawn 3 years ago, but the seller still seems somewhat active. We will try. If you are the owner of this terminal, please contact us here! Thank you!

Vintage Computer ENTREX NIXDORF SIEMENS OLD Rare Collectible 16-bit Front Panel

I was first notified of this auction on July 20, 2019. This was being sold by Dick DuBois, a former employee of Entrex/Nixdorf during the reign of this system. So, he would certainly be able to verify its origin.

He sold it on Aug 25, 2019 , 1:05AM (36 days later) for his ask of $295 (but not to me, sorry). Congrats, Dick, and I'd love to hear from the person who bought it, to hear the story behind its meaning to them, and how they may intend to use it. So, if you're reading this, please click the contact tab at the top of my website here, and drop me an email!

My novice commentary: This appears to be most similar to a "half-height" DCC D-116 front panel, but clearly different, in that it is lacking all branding and model markings, the key/lock tumbler barrel switch and/or hole for such. (more differences noted by me at the bottom of this post)

It does indeed look very utilitarian, as if it was truly intended solely for testing, and never to be placed with a customer. Dick confirms this in his auction description, below.

But I'd love to get the feedback of someone more knowledgeable on this system. From my Digital Computer Controls - D-116 16-Bit Computer Handbook, here's the comparison:

Very Rare Vintage Collectible Computer 16 Bit Front Panel

ENTREX / NIXDORF / SIEMENS

This panel measures 19" X 5"
and was mounted in the front of the
CPU chassis during troubleshooting.
It was not usually left on site.
We are not sure if it still works
so we are selling it as - no returns

A real nice piece of vintage computer history.
Nice collector's item.

Nixdorf 480 80 Series Operations Manual

I acquired this from https://www.ebay.com/itm/133104961852

While it seems to be from 1979-1980, and the Data/Scope Keystation style has changed to the upgraded style (and they even call it a Data/Terminal Keystation now), my hope is the system had changed little else since earlier versions...or so we can hope!

Anyway, here is the entire manual, scanned. Enjoy!

**BONUS: I even scanned the inserted notes and extra printed pages that were in this manual, in the exact location between the exact pages that they were found, to preserve the context, in case they were significant there. So, when you see things that don't look like the manual right in the middle, now you know why...

The key to the Entrex system was the Scanner board and software...

Barry King July 24, 2019

Hi AJ. Sorry for the extremely late response. I have been very busy the last months. The key to the Entrex system was the Scanner board and software developed by 2 or 3 guys at MIT as a project to complete their Master's. Without those two it was just a regular Data General mini-computer. The scanner polled each terminal for service and did it extremely fast.. Each terminal was directly connected individually. From the Entrex/Nixdorf days, all I have are a handful of terminal connectors and a Field Service book. If I can provide any helpful info just let me know. I will watch more closely. Regards, Barry

Vintage 1972 Core Memory Motherboard - Digital Computer Controls - Collectible

Original eBay Auction eBay Auction Archive

Vintage 1972 Core Memory - Motherboard Digital Computer Controls - Collectible

The title says it all. The board is 15" x 15". Would look great hanging on your wall. All that power...

BTW, as far as I know, this board does not work, so...Non-working. It is presented for the Art that it Is.

Component side has two areas of slight oxidation. See photos. I didn't attempt to clean on the off chance that I'd do something I shouldn't. Otherwise board is very clean.

key tronic corp. Keyboard 065-01149- on Entrex Data/Scope

Now that we can finally see more close up what the internal workings of an Entrex Data/Scope keyboard look like, we can see the manufacture and at least one of the model numbers:

KEY TRONIC CORPORATION

065-01159-

And then the stamped 003 after that. Not sure how significant that is, but since it's stamped and the other numbers are etched directly into the board, it seems like those last 3 digits can change easily, where the previous digits are the true model number "set in stone" for this board.

Let's see what insights the experts over on Deskthority.com have on this...

Entrex Data/Scope in Atari 400 800 XL XE catalog - ZiMAG

I came across this advertisement for ZiMAG magnetic media (clearly quite vintage early 80s) at

http://www.atarimania.com/catalog-atari-zimag-_300_8.html

And on PAGE 10 (or 11, depending on if you count the front cover as page 1), we clearly see an Entrex Data/Scope! What's that doing in there? Well...let's take a closer look...

Firstly, the chassis cover is painted this very nice dark charcoal color, which matches the advertisement colors very nicely. I've never seen one in charcoal before, only white and off-white (or yellowed with age). I've seen red, but then again, it could be for exactly the same "display only" reason that I suspect here. Here's why I say this:

It sure looks like the blue and white keys have been all painted black, and that a few red and black keys have been moved around a bit. (Note that only a few black keys show the white lettering, but most are just plain black).

For example, the HELP! key should be on the top of the right (atop the right vertical row), but instead, it is on the extreme left middle of the main key group, which should be a red RESET key instead of the black HELP! key.

It sure looks to me like this keyboard has been modified for the aesthetics of the advertisement, rather than functionality. Still, VERY nice job...from first glance, it is quite an attractive piece in this context.

What I'm more interested in, is the code on the screen. Looks like standard line basic to me...was it really displayed on this Entrex, or superimposed there? It appears a bit too close to the top edge to be on a CRT, and they were all black & white screens, displaying only 480 characters (12 rows of 40), which is WAY larger letters than what se see here... BUT, who knows?

Entrex Data/Scopes (Keystations) spotted in Germany

We JUST found TWO Entrex Data Scopes on eBay.de from March & April 2018...in GERMANY!
And they SOLD! And we missed them...

Haben Sie eine dieser Data/Scope Keystations gekauft? Bitte kontaktieren Sie uns, wenn Sie es getan haben!
Did you buy one of these Data/Scope Keystations? Please contact us if you did!

March 5, 2018 222852550966 (archived by me)
(original auction, now removed, was at http://bit.ly/312R6Xc )

AND

April 28, 2018 222930393667 (archived by me)
(original auction, now removed, was at http://bit.ly/31bKSob )

On first guess, one might think that these two auctions are one single Keystation, listed twice. However, while each of them are remarkably similar, a closer inspection of the labels and serial numbers indicate that they are, indeed, two distinctly separate Keystations.

So, how did we miss these? I guess we failed to learn how to set up eBay alerts in GERMANY...that's why...ebay.de only, NOT reported on ebay.com!

And hats off to Al Kossow at bitsavers.org

Even though this particular model can't be found at

http://bitsavers.org/pdf/pertec

Al knew that he had seen this tape transport as a [rebranded] Burroughs Series 9491 Magnetic Tape Unit, so he was able to provide the exact correct manual! Thank you, Al!
