The MERA-ELZAB 7951 Terminal for the Polish "SEECHECK" system - Clone of the Entrex Data/Scope

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 from the Entrex 480/Nixdorf 620

I actually acquired one of these on November 19, 2021

during an already-scheduled trip to Europe, I added a visit to Poland just to see (and hopefully buy) one of these terminals...and against all odds...I succeeded!  It's a wild story, for another video and post...

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.

And a while later, I found this Twitter feed which references both this Reddit above, AND my website here for reference, Nice work!

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

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.

Greeting,

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.

The above 2 images were stolen from notes.whatthefuck.computer

Below images were taken by me.

DeSegi - C64 in the [Entrex / Nixdorf] terminal

From https://forum.classic-computing.de/forum/index.php?thread/17730-c64-im-terminal/&postID=260682#post260682

According to the forum discussion thread, If I translate and interpret it correctly, DeSegi bought this as it is on eBay in October 2019.  That's awesome!

But the questions remain...

• who did the customization work? 
• which keyboard style was this terminal before this was done?  
• Do the original electrical components and/or Key Tronic keyboard still exist?

Nixdorf CEAG Dominit 820 Power Supply

This power supply bears a resemblance to the Nixdorf 620 power supply shown here, but is likely for a different system...possibly Nixdorf's 820?  Seems logical, given that the power supply numbers match the Nixdorf-assigned system numbers.  I'm just archiving it here for reference...
