We are currently using a little box with a Z80. It is manufactured in small quantities to interface a Hawley mouse and chord board (for the empty hand) to the IBM PC and Zenith 100. The box can change to different settings and modes by receiving instructions back from the PC. For the PC the keyboard, mouse and chordboard all three plug into the box which then plugs directly into the keyboard port. The Zenith was a little trickier since it does not have a detachable keyboard. For the MAC there may be better ways to solve this problem, but we dont have the inside mac documentation. Assuming there is nothing on the mouseport inside the mac to sense any currently unused pins, one idea is to use the existing MAC mouse port for coordinates and one button. Then put the other buttons into a different port on the back or into the keyboard port. There are a couple of things we would like to know. Are there four unused codes we can send to indicate the other two mouse button up/down states? Is there some way to send info from the mac back to the keyboard port so the box can set its modes? -- kirk
