That's a shame. Many of the WordStar holdouts actually like their writing machine to be some old reliable computer without modern distractions. It isn't just the software, it is the whole experience. It runs one program at a time, no internet, now notifications, just reliable typing on what's probably a mechanical keyboard that has exactly the right feel.
Unicomp makes leaf spring switch keyboards that are the modern day equivalent of IBM's beloved PC keyboards. They are too loud for a shared work environment but perfect for home use, assuming you don't multitask during a meeting with your mic on, anyway.
Leaf springs are different switches. Unicomp makes buckling spring keyboards - which are not "the equivalent" of IBM's Model M keyboards, but they actually are the current brand which makes the original Model M keyboards. (They were branded "Lexmark" earlier - after IBM had founded a spin-off company for them.)
They have become less sturdy over the years though.
You are correct - I went from memory and misremembered the name of the switch type in the Model M keyboards. Appreciate the clarification. What I meant by modern day equivalent is the fact these newer keyboards are available with USB.
