I lucked out and found a working IBM Model M keyboard at a thrift store that I would like to use with my Mac Mini running OS 9, but it's from 1984 and lacks the Windows key that typically maps to the Command key on a Macintosh. Googling this particular issue has proven tricky given the generic nature of the keywords, so I apologize if the answers I seek were easy to find and otherwise obvious.
I'm using a PS/2 mouse and keyboard to USB adapter I picked up from Amazon that seems to work fine on my PC and my Mac Mini - I can pull up the link to the actual product if necessary. Plugged into it are the aforementioned IBM Model M and a Logitech Marble Mouse two-button trackball. My basic goal was to find some kind of software that would allow me to remap the (missing) Command key to another key on my keyboard(maybe an unused Function key) through software. I've tried to use Key Swapper, which crashes instantly when I try to load it, and QuicKey, which in some cases causes Finder to force quit and in others seems to hardlock my system during startup(after the desktop appears but before the Finder windows can display) but in all cases ends up freezing my system. In the case of QuicKey, i've tried creating a new base Mac OS 9 set of extensions and enabling just QuicKey aside from the base extensions, but this hasn't changed the freezing results.
Are there any other applications/control panels I could try to remap one of my existing keys to take the place of the Command key?
