I ordered one of these and returned it instantly. Very cheap and weird compared to nice and modern mechanical keyboards you get today. I really wanted an original model M but didn’t want to deal with weird ps2 conversion stuff.
I suspect some motherboard companies have people who still cherish their Model-M's, because support for them seems to be flawless. How many other completely unmodified thirty-plus year-old peripherals can you plug into a brand new computer and expect to just work?
I think modern cpus include the ps/2 handling in their legacy cruft section, so it's just a bit of signal routing and a connector.
