I was lucky enough to bag one of these on eBay 10 years ago, someone was selling a god awful computer and I asked if I could just take the keyboard for a vintage computing project. Cost me 10 pounds. I bolt modded it, but eventually sold it as I wanted to fund my HHKB addiction which is a solid keyboard, just more portable than a Model M

Thankfully, a friend gave me another Model M recently, and it's now awaiting a clean and a cable
