Hello, I've been programming the Mac for quite some time and have always appreciated the 'Macintosh Way' of accessing the hardware through the system routines provided. Up to now I've been doing applications programm- ing and these routines have served me well. At this point, I need to know more about how and where the hardware is mapped into memory. For instance, accessing the serial ports from the serial drivers has always worked fine, but to write my own drivers, I need to know more about the hardware. Where can someone who isn't a registered DTS developer go to get such information? I'd like to know more about programming the ZILOG chips as well as SCSI, NuBus, the Sound chips and such. Specifically, I'd like to know how these devices map into memory on my IIcx physically so that I don't need to use the definitions provided by Apple. I know such practives are generally frowned upon by Apple for software developers, but my interests are in hardware specifics. If someone can give me pointers to this nitty-gritty info, I'll wash your car.
