Currently got this one on my work laptop. Model M terminal board with internal converter. The only layout changes I made versus a normal 102-key are that RCtrl is is a Windows key, and the four keys along the right side of the numpad are =, -, +, and the normal Enter.
I wish I could get one in a 60% layout. My desk is too small for my big ones.
Unicomp has buckling spring boards in TKL. A bit pricy, but cheaper than a vintage Model M "Space Saving Keyboard". For 60%, the closest thing I know of is the even more expensive Model F Kishsaver layouts (adapted from an old and insanely pricy banking keyboard from ~1980). I have never tried one of their boards, but I know they exist.
Thanks, I was aware of the model F project but didn't realize they had anything other than very large layout options. I have 4 original model M's, (two are broken), but my desk is too small with my work and personal computers. (I tried a keyboard switch, but I gave up using it after typing to the wrong computer one too many times)
I also work both from the same desk. I keep the home keyboard and mouse on a deskmat that I just slide the very edge when work actually needs my undivided attention. The Model M's don't come out to play too terribly often, and most of my weird little "1800" layout variants that I make as a hobby take up a good deal less space. Still, sometimes you just need some pingy buckling spring goodness in your life.
