I've written OS-9000 drivers for the MPC860 and firmware test code for the
MC68360 (the predecessor to the 860, CPU32 instead of PowerPC). If anyone
is looking for someone to include in discussions of NetBSD on an MPC860 or
MPC8260, please add me to the list. I'm looking into a design now that
would use one or the other of these chips.
