[cctalk] Siemens DVA 2002 Ferrite Core Memory, c. 1961 – looking for a collector

Dear ClassicCmp community, I am looking for a new home for a rather special piece of early German computer history: An original ferrite core memory module from a Siemens DVA 2002, dating from approximately 1961. The original accompanying label has survived with the module and identifies it as: ● Ferrite core memory from a DVA 2002 ● Dating: circa 1961 ● Memory capacity: 80 × 14 bits ● According to the contemporary description: approximately 840 characters ● The ferrite cores were threaded by hand The module appears to be in very nice and largely original condition. The core matrices, wiring and contacts are clearly visible, and the historical documentation accompanying it has also survived. The Siemens 2002 was one of the early transistorized computer systems produced in Germany and represents an important part of early Siemens computing history. There is also a personal connection to Siemens in my family: my father, Hans Sessler, was the head of a Siemens data center. The module comes from this family context and our connection to computing technology of that era. I am currently parting with a few special objects from my family collection for personal and financial reasons. However, with this particular piece, it is important to me that it goes to someone who understands and appreciates what it is – ideally a collector of early computers, a computer historian, a Siemens specialist, or simply a serious core-memory enthusiast. Therefore, I am inviting serious offers rather than setting a fixed price at this stage. I am located in Germany. International sale and carefully packed shipping can be discussed. I would be happy to provide detailed high-resolution photographs of the front, back, core matrices, connectors, labels and accompanying documentation to anyone seriously interested. I would also very much welcome any additional information from members who may be able to identify the exact configuration or historical context of this particular Siemens DVA 2002 memory module. Please feel free to contact me directly with an offer or further information. Best regards, Julia https://urnenwerk.com (+49) 151 20 76 66 22 menden(a)urnenwerk.de
