Yes your quadra 605 will run NetBSD.  Mine has been for quite a number
of months (quite happily, I might add).

The difference between a 68040 and a 68LC040?  The "lc" chip lacks an
integrated floating point processor -- the "Full 040" includes one.  The
math functions that a 68040 does in hardware must be performed via
software emulation in the 68LC040.  For certain things it's much slower.

Your machine came (as stock) with a 68LC040.  They're pretty cheap to
find these days -- you'd be well to consider getting one.  They're quite
easy to install and your machine will be a better unix box with it.

I upgraded the 040 chip in my machine long before I ever heard of
NetBSD, so I've never run it with the LC chip.  With the full 040, it's
fine.
