   @TechTangents I think that's the size HP used on their HP-9000 drives?

     @TechTangents it seems this size dates to 1982, so it might just be that they had no interest in compatibility with the (then-new) PC format and made their own standard

     @foone Yep, those are Sony drives from the early 80s too!

     But I cannot figure out why they are that exact height which doesn't match anything else I can find. I'm guessing they predated any standard for the smaller drive bay.

     @foone My next video is about the origins of the 3.5in floppy which is why I'm curious about this. It predates the PC so it was doing its own thing. HP was actually the 3rd company to release a product using it.
