Update #3: I have found many examples of rare IBM gear from the 1960s inside the warehouse. These include: 8x IBM 029 keypunch keyboard Boxes of IBM keypunch parts 2x IBM 552 Interpreter 1x IBM 083 Card Sorter 1x IBM 4505 Display Station I have been unable to find anything about the 4505 display station. Does anyone know any details about this item? It resembles an IBM 2260, but the keyboard is not built-in, as in the 2260. I am taking offers on the items listed above. Thomas Raguso
