Micro National PC
Key Tronic Butterfly switch (Linear; spring over foam & foil)
This board is a bit of a mystery. It was listed for free on r/MK to the person willing to pay shipping, and I snagged it. When I received it, none of usual adapters or converters would get it working with my PC. I ended up shipping it off to Hagstrom Electronics where they performed a series of protocol diagnostics on the board, and put together a USB converter that spoke the one-0ff XT protocol of the keyboard and translated it to USB.
The keyboard layout is similar to that of the IBM Model F, but it definitely doesn’t the feel the same as a Model F (or Model M). The Butterfly switches feel nice nonetheless. This board was about the journey, and the relationship I made with Stan and the other fine folks at Hagstrom. 🙂
