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.
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)
