Here is a Nixdorf 820 with the ROD memory https://www.icloud.com/sharedalbum/#B0Y59UlCqNHCjx https://www.icloud.com/sharedalbum/#B0Y59UlCqNHCjx https://www.computerhistory.org/revolution/memory-storage/8/264/1116 https://www.computerhistory.org/revolution/memory-storage/8/... This computer earned listing for this innovation. https://www.computerhistory.org/revolution/memory-storage/8/264 https://www.computerhistory.org/revolution/memory-storage/8/... Which puts into context. I also included the story of it's previous life. My thinking is we are focused on making circuits too small. We need big circuits that make big but simple decisions. I was collecting pre-microprocessor computing artifacts for a while. I now need to get sit down and figure out what I have. In the meantime I use them as reference idea to feed my development of a 100 year computer.
