Still, it may be worth posting the various permutations of your porting effort so far.

Perhaps the MMIO functions will allow all the code to remain in C? I assume you made the swim_write and swim_read macros use them? I think the code for turning off interrupts must also be changed for PowerPC. Until that's handled properly, it won't matter what code you substitute for the m68k assembly. BTW, which m68k Macs had SWIM II instead of SWIM I? ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
