Not really gonna simplify vehicle designs much, the door still needs to be bigger to support CCS2 in Europe, Chademo in Japan, and whatever China is using. It is easier to have a big door that fits any socket type than it is to have to restructure that entire area between countries.
Hm, must have googled that spec wrong, to be fair, they don't list it on the product page.
Unicomp Keyboards used to be rather derided due to declining quality resulting from aging manufacturing tooling, making them a mere shadow of the Keyboard IBM made. That being said, their "New Model M" uses new tooling. The situation seems to have improved quite a bit on this new model as a result. That being said, at $125 I find the New Model M rather pricey for what they are: a basic keyboard with limited customization and mere 2-key rollover. If you really want buckling springs and want them brand new, it is the way to go, otherwise consider buying an original Model M used or buying a regular mechanical keyboard with clicky switches.
Filament is likely waterlogged. If so, then it needs to be dried using a filament dryer or oven.
