Well mac68k.html is not very clear about the FPU thing. The first
paragraph seems to imply it isn't neccessary but later on in the
Suported Hardware section, a FPU is required.

And then, there isn't much help of where the FPU needs to be for
it to be supported.

Like the LC II (which I have) doesn't come with a FPU socket but
is listed as supported. Does this means some kind of LCPDS FPU
expansion works in OpenBSD? 


And I though that the FPU emulation was broken in OpenBSD anyway?
(Wouldn't that be the reason the FPU is required in the hardware
section?)


When I got my complete LC II from street garbage, I didn't even try
to get OpenBSD on it because I thought it was unsupported.

But it made me want a supported one so I had come up with a list
of the good mac68k: 

Quadra 800, 650, 700 and 610. (in this order)

(because they come built-in with supported 68040, ethernet and video
console, so no need to get extra parts).

Anyway, I have a Quadra 650 since 2 weeks now. I might move the
hard-drive over to my LC II just to prove software FPU is working
or not.
