I am trying to find out how to modify the device driver for the Mac+ keyboard so that I may use another keyboard with a somewhat similar protocol. Upon looking through _Inside Macintosh_ there are descriptions for various drivers but not for where the Keyboard driver is and how it handle key up/down events. The serial protocol is described etc. but what I need to know is what system interface code would have to be written and what vectors would have to be modified etc. Does anyone know how to do this or where to find out? Is this even possible, or is all this etched it in rom? Thanks in advance, Marcos Salganicoff GRASP Lab Univ. of Pennsylvania Phila. Pa. (sal@grasp.cis.upenn.edu) Marcos Salganicoff
