View of the remainings upon arrival

Story:

 In March 2012, there was a discussion on the classiccmp mailing list about some "remainings" of the former Computer Museum Aachen (CMA) in Germany. As far as I understood, a few years prior to 2012, the building in which the museum was residing, had to be torn down which is why the collection had to find a new home. Eventually, most of the collection could be saved thanks to the Computer History Museum (CHM) in the USA and a donation of SAP. The latter made possible the shipping from Germany to California from a financial point of view. The collection is since then known as the "SAP collection" and stored at the CHM, of which some artefacts are exhibited for visitors to be admired. However, some bits and pieces, found their way in an old trainstation warehouse in Dortmund. A very motivated person, Alexander, got informed about the location of the vintage systems by a local fellow and, in turn, tried to locate and contact the tenant of this warehouse via the landlord. It turned out that the content stored there had to be cleared within two months, as the building was going to be sold. Thankfully, Alexander then tried to contact collectors willing to save these remainings, as everything not saved would otherwise have been scrapped.
A post in a forum dedicated to Robotron computer systems (Vintage computer manufacturer from the former German Democratic Republic) was placed with images of what was stored in the warehouse. The approach was "first come, first serve" in order to give away for free everything to collectors, whoever wanted to save these.
Then, a list member of the classiccmp mailing list posted a link to the Robotron forum thread. There, I was able to contact Alex who managed the give-away of the computer remainings in order to ask him for information about and identification of the parts. A lot of phone calls and several visits to the warehouse followed over the next three months during spring 2012.
During my first visit there, I took the picture that is shown above.

A friend of mine and I drove to Dortmund with a 7.5 ton truck.
When we arrived, I was literally shocked to see such amounts of historic computer and peripherals "artifacs" stored in a warehouse. The roof was in bad shape (water leaks) and pigeons were flying in there. The hardware surely saw better storage conditions in the past.

On site, we met very friendly classic computer enthousiasts from the Robotron Museum who came to rescue systems and parts for their collection. There was a very nice atmosphere in trying to help each other to move heavy parts and cabinets around, to part with the bits in a fair way and to identify and estimate the conditions of these remainings. Those are the days I appreciated a lot: When you can meet new people who share this passion about vintage computing and save systems together from being scrapped. And that's how I have been knowing the classic computing community in Germany up to that point in time.
However, for the first time, I also made less pleasant experiences in this field.
Soon, the discussions in that robotron forum thread dealing with the CMA remains where marked by rough tones of a person who stated that the remainings left behind by the CHM in that warehouse where "rejects" and therefore not worth or at least not interesting to be picked up because of probably being incomplete. This same person called Alexander (who discovered the whole thing and opened the thread to save these systems) as unfair, as he felt the systems were already rewarded to others under doubtful circumstances.
Another bad surprise, we had to face, was the behavior of a collector from north-east Germany who was at the warehouse earlier than me. This person took the opportunity to take with him two incomplete EAI 2000 analogue computers for somebody else, I originally was supposed to deliver to. The person in charge at the warehouse confound that guy with myself and asked him, if he was the one supposed to bring these machines to the person, who claimed interest in these. He said "yes" and took everything with him. This was for me the first time that I had to face such a doubtful behaviour from somebody with the intention to put hands on vintage computers no matter what!






remainings
                      overview View from one of the two entrance doors: In front of the white cabin can be spotted two DEC hierarchical storage controllers (HSC) and a TU78 or TA78 tape drive. These were put aside for a DEC enthousiast to be picked up.
In this picture can be seen a large disk drive (to the right of the terminal screen), and partially a large printer (with a blue side panel) and a CDC 844 Multiple disk drive system. Additionally, there are to IBM-labelled teletype consoles facing each other. The large white cabinet in the picture was a CDC communications controller.
Here can be spotted close to the wall a Hewlett Packard 9 track system (7970) in an angelled, so-called "low-boy" cabinet, and a large Calcomp plotter in blue in front of the tape drive.
The first item in this picture that draws attention is the Calcomp tape drive in light blue to the left. In front of it stands a CDC disk drive. One can also see that on one particular item are a lot of pigeon droppings.
In this corner of the warehouse were located an ICL 1900 tape drive lying on the side on a pallet, a Telefunken printer (dark blue, behind the ICL tape drive) and a large I/O unit from a CII Honeywell bull 6000 series computer system.

Experiences:


On site, we met very friendly classic computer enthousiasts from the Robotron Museum who came to rescue systems and parts for their collection. There was a very nice atmosphere in trying to help each other to move heavy parts and cabinets around, to part with the bits in a fair way and to identify and estimate the conditions of these remainings. Those are the days I appreciated a lot: When you can meet new people who share this passion about vintage computing and save systems together from being scrapped. And that's how I have been knowing the classic computing community in Germany up to that point in time.
However, for the first time, I also made less pleasant experiences in this field: I was supposed to take two incomplete EAI 2000 analogue computers for a fellow collector of analogue computer systems. However,  a collector from the region of Greifswald who was at the warehouse earlier than me, seemed to be very interested in these, EAI systems, too. Alexander who organised the give-away in the warehouse confound that guy with myself and asked him if he was the one supposed to bring these machines to the analogue computer collector. He said "yes" and so the EAI systems were gone and I could not bring these to the analogue computer museum as planned. This was for me the first time that I had to face such a doubtful behaviour from somebody with the intention to put hands on vintage computers!



Impressions:




Inspection of a large Honeywell Bull reel tape drive using vacuum columns (OEM from Control Data Corporation): The drive was found on the floor for an unknown reason. The tape drive seemed complete, i.e., no parts seemed to miss at first glance.
On the right picture, one can spot the mechanical mechanism behind the door that is used to automatically drive down or up the glas window in order to access the tape. We found the glas broken when we inspected the tape drive.
Loading the cabinets into the 7.5t truck. The loading weight limit was reached fairly fast! The winner of the weight contest was the CDC 604 tape drive with almost 600kg (1200lbs) according to specifications!
Everything was secured for the ride and the ramp is ready to be closed after my trusted driver refused to load additional systems or peripherals (truck load!). One may spot the GE Terminet printer on the right side in the truck.
Rüdiger and other team members from the Robotron-technik museum were also present. There were able to rescue two ESER disk drive units and many more artefacts! A link to their article describing their rescue operations can be found at the bottom of this page.

So what was saved from the scrappers?


Here is the summary of what I was able to offer a new home:

Additional detailed information about the rescue operations in Dortmund can be found in a nice article written by the robotrontechnik team.
