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:


(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



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 !!!

Paul Cicchetti Entrex Records/History

So, that Frenchtown, NJ auction, from which I acquired our first Entrex 480 system chassis & [some] system boards....Who paid to store these since [what turns out to be] 1981?  His name was Paul Cicchetti.

There's a lot to say about Paul, as we learned from the items we acquired from his storage units auction, but this one thing is the most relevant.
