[comp.os.minix] Help needed on a Zenith calendar chip

MJP104@PSUVM.BITNET (11/15/88)

Dear minix users,

     I need some help.
     I am currently working on a project for my college minix class. In short,
I have decided on one of the options. The option asks that I change minix in
such a way that instead of asking the user for the time and date when it is
booted up, it will take the time and date from a calendar chip that is run
on a battery to keep time when the computer is turned off. The unit i'm working
with is a Zenith data systems ZDF-2255-BK. I asked a systems person here for
more info. Here it is for those of you who understand the meaning:

     * The INT 08H instruction keeps track of time of day.
     * The chip is an 82C432 used to synchronize all functions for 82C434
     * Active transition is high to low.

     I need to know other things such as what port it is on, whether or not it
can be accessed by address by the minix code, etc. How should I approach this
project? Any and all suggestions will be greatly appreciated!
