A Forgotten Machines T-shirt visits the MHKI and the Mera 7951 in Katowice

These pics were taking by my friend Kris on his visit today to the Muzeum Historii Komputerów i Informatyki (Museum of the History of Computers and Information Technology) in Katowice, Poland.

What an honor it was to see him there, wearing our branded T-shirt!  I cannot wait for the time to come for me to visit this wonderful place myself!

You can actually see the Nixdorf badge pasted right over where the Entrex logo silkscreen would have been in the lower left of the plexiglass on the screen

vs

reference our JCPenny Entrex Data/Terminal Here

Notice The Love Boat model has the 029 keypunch-style keyboard

Reference our two Nixdorf-branded Trapezoid Terminals here

Next, find the original 3:4 aspect ratio format and show HQ screen shots

AND

Identify the foreign device under the computer, which may be a real (or fake) punch card reader.  Is this also a Nixdorf product?  Could be...

Perhaps there was some Nixdorf sponsorship going on in this episode??

Cortron 35-500179 80-350253 Keyboard for the Entrex Trapezoid Terminal

Notice that the build date on the ID tag of this keyboard says 1986, even though that is a full 7-8 years after the build of the rest of the terminal (1978-79).  The IC chip dates all seem to back this up on the keyboard (84-85 dates) and the terminal (78-79 dates) This is curious, but not unheard of.

Since only 5 of these terminals are documented to survive in the world so far, what are the dates of the other 4 keyboards?  We shall find out...because we have 3 of them, and we hope to get dates from the other two!

(my archive on Google Drive)

All of my analysis brings me to the conclusion that this software company (if it is a software company) had NOTHING to do with the Entrex 480 systems that this website is about.  Perhaps by 1989, the trademark on the original Entrex name had expired, and this small software development company took it over, and repackaged some existing games by Softech Microsystems and maybe added some of their own features?

Perhaps enthusiasts in the DOS game genre can speak to this...

Compare to the previous year's VCFMW 2021 setup

Nixdorf Mini Computer SIEMENS Rare Collectible 16-bit System 480 Front Panel (Brief eBay "flash")

Interesting item from the same seller as this removable front panel:

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

(while the eBay ID is different, it is the same seller, Dick Dubois, former Entrex engineer)

In one day, the listing was created, then removed, and not yet relisted.  Interesting, since he has another one nearly identical, that has been listed steadily for 3.5 years or more.  What happened to this one?

Nixdorf 600/55 "Trapezoid" terminals in use at Brooksville, FL courthouse September 1982

Formerly at https://outlet.historicimages.com/products/rrx89957 (now archived)

Nixdorf 600/ 55 computer system improved record keeping at the Hernado County Circuit Court, where thousands of pieces of information are processed and stored 

September 20, 1982

The new Nixdorf 600 / 55 computer system has improved record keeping at the courthouse to the point where a person using one of the terminals will be able to locate a document delivered to the building as recently as 15 minutes earlier.

BROOKSVILLE -- It almost has become passe to marvel at the wonderful things computers can do to make our lives easier.

But perhaps nowhere are the benefits of "computer age" more apparent than in an office like that of the cleark of the Hernando County Circuit Court, where thousands of pieces of information are processed and stored each day.

The clerk's office got its first computer in 1974, but that machine was mainly to produce "hard copy" -- computer printouts that simplified the process of finding any of the many records stored at the courthouse, according to Harold Brown, the circuit court....

We just bought this photo, and the moment we did, the original page disappeared.

Entrex "Redifon Seecheck" system located on web page from 2003 - scrapped long ago unfortunately

Original page at http://www.lupinek.com/pocitace/redifon/redifon.htm
Translated from Czech:

REDIFON

Many of you can't imagine life without computers, it would be hard for an accountant today to calculate wages without a payroll program, the youth would probably be bored without Doom or Unreal Tournaments. Even the price of regular PCs is getting lower and lower and so these are now commonly available to members of households. 

It wasn't always that simple. The proof is in these photographs of the now scrapped Redifon system, which was used until 1996 to prepare the payroll and cost accounting for the company. The whole thing consisted of about 30 terminals, two tape drives, one hard drive (and a heavy one at that), three high-speed cylinder-head printers, and one central unit (if memory serves, it was run by an 8080 CPU and had 128kB of RAM).

Terminals (or Redifon "Workstation")

External memory drive with an incredible 40MB (very decent for the time)

Control computer with i8080 CPU (Redifon "Server") + tape

High speed printer (speed 800 characters per second - that's a page in 1,5 sec !!! )

 

That's how it was back then !!!
