Document Description
This single-page color-coded diagram depicts the complete patch panel (Programmierfeld) layout for the Dornier Analogrechner 240/720 analog computer. The diagram serves as a programming worksheet: the operator records the program name in the “Programm:” field and the programmer’s name in the “Programmierer:” field at the bottom of the sheet.
The central graphic is a detailed, color-coded representation of the patch panel’s jack matrix. Each row of jacks corresponds to a computing element or bus. The color coding distinguishes functional groups of computing elements:
- Yellow rows — integrator or summing amplifier groups
- Red rows — computing element patch points (amplifier inputs/outputs)
- Green rows — reference voltage or coefficient potentiometer points
- White/grey rows — general interconnect or output bus jacks
- Blue squares (left column) — element-type identifiers or mode-select indicators
Along the left margin, a label reads “EXTERNE SCHREIBBOGELEITHINDER” (External bus/routing connectors), indicating a section of jacks dedicated to interfacing external signals or display devices.
The right portion of the panel shows additional labeled groups including “SCHALTER” (switches) and “VERGLEICHER” (comparators), as well as section labeled “STECKFELD” (patch field), confirming the right-hand cluster handles logic/comparator and switching functions.
The overall layout reflects the 240/720 designation: the system accommodates configurations combining the DO 240 and DO 720 computing modules, providing a unified patch field for programming complex analog simulations.
The blank “Programm:” and “Programmierer:” lines at the bottom are intended to be filled in by hand to identify a specific program configuration, making this sheet usable as a reproducible programming record form.
Translation note: The document contains no running text beyond labels. All technical annotations above are transcribed and translated from the patch panel diagram labels as rendered in the scanned image.
