 DEC made adapters that went from differential to SE so that you could

 bi-directional and transparent or not though.
 
 I think you'd be better off looking for a differential host adapter....

I don't think there is any opensource software that runs the one
sun differential adapter that I am aware of.  The RSM 2000 array
calls for a pair of those adapters to run the array from the host end.
But, I was not thinking NetBSD (or any opensource stuff) ran those.
I did see one adapter listed on the net.

You raise an interesting thought about the DEC stuff, though.
Maybe I should check those things out.

Thanks
