Good to know. I thought I've thrown mine away years ago when I moved 10 years ago but just found in one of the boxes I haven't opened since then. I tended to use it with my mac pro 2013 but now that I know that it takes some effort to get it working with monterey
I might ditch it for a few bucks at a refubisher. I'd prefer using it with my mac pro though.
The other options would be keeping it for some other device or even mod it with an arduino and a thinkpad trackpoint. The space over the T-cursor-keys should have enough room.
