Sure is... lol
I read one time that the computer system capabilities on the space shuttles stayed at the same level as an early intel 286. It was explained that this was to make it slow and reliable on purpose. But I’m not sure about this thing here still using floppies.
I had heard a story that they could fly the shuttle as an emergency backup with 2 or 3 HP programmable calculators.
I’m guessing that was for navigation and not really to “fly”....but who knows....
