In the early 1980's, plugs with low pin density like DB-25 were common on home computers. The industry was still relatively small, not everything in the manufacturing chain was automated. I assume a lot of those early cables were soldered by hand. I'm sure higher densities were possible, but if a cable cost $10,000 or something it wouldn't have been practical in a consumer product. So, when did the physical manufacturing technology in the consumer computer market reach a point where you could travel back in time with a USB-C diagram and use it in a product?
To scope this, I am not asking about performance or protocols. A full modern USB software stack takes more memory than existed on a home computer in the early 1980's. That's fine -- I am just asking about the manufacturing of the physical cables, plugs, and sockets. Even if a 1980's USB-C would only have run at a few KBPS, and only worked as a simple serial connection.
Edit in response to a question to add : The ability to flip USB-C is interesting, but not directly relevant to the question. I am assuming a microcontroller or other circuit could handle the flipping quite early, at the cost of expense and possibly speed. But the question is specifically about just the physical manufacturing, and how it evolved over time to make it practical. A USB-C connecter has small springs within the plug, extremely fine tolerances in the hundredths of a millimeter. Was it even practical for a cable manufacturer to source exactly the right steel for the internal springs in the connector before widespread Internet connectivity made it easier to find suppliers?
