My uncles dairy had a datamaster in a back office that they used for the books, etc. I wonder what happened that that, it's no doubt stuffed into some haybarn loft.
My uncle had a business with an IBM minicomputer: a System/36. It was the size of a large freezer. It also used 8" floppies! It took a "magazine" of 10x 8" floppies and could swap between them. It looked like the system in the top photo here: https://en.wikipedia.org/wiki/IBM_System/36
