Has anyone done this, no matter how ugly? I've got a couple of Mouse
Systems meeses (plural of mouse, right?) that I'd like to convert. I
know it's going to be a bit of work, but if someone has already puzzled
it out, I'd appreciate hearing from you.

Someone HAS done this, and posted it to BIX last month. I'll get it sent
up to ab20 if anyone's interested. The only problem is that since the
hardware is read directly for a button click after a Guru, you'll still
need something attached to the mouse port for that. (Or just give the
keyboard the three-finger salute.)
