The mechanical parts in those old Walkmans are just built different. No digital processing or backlit screens to drain power, just pure analog doing its job with almost nothing wasted. My dad still has a 70s receiver that runs circles around modern amps in terms of energy draw, and the sound is way warmer too. It makes me wonder if we traded efficiency for features we don't really need.

Figure out what's actually changed before you go all detective mode on it. I mean, street names get renamed all the time for dumb reasons, like honoring some mayor nobody remembers or fixing a duplicate that confused the mail carriers. Half the time it's just a good old typo that got copied forward for forty years. Idk, it's a fun little hobby to kill an afternoon with, but I wouldn't call it a rabbit hole unless you're finding actual court records or something.

Read a writeup in Scuba Diving magazine that said those home repair kits only work for tiny pinholes and minor tears, not the kind of stress a zipper gets on a real dive. They tested a few brands and the adhesive just doesn't hold up to saltwater and constant bending. You already dropped serious money on a drysuit, so cutting corners on the zipper seems risky, especially if you dive deep like off Louisiana where a flood means a cold, bad day. Getting a shop to resew it with the proper heavy duty zipper is the only fix that's ever held for me. Next time, maybe check if your suit is still under warranty first because some manufacturers cover this sort of thing.
