The issue was it was very crowded on the right side of the
card when doing board layout with the nubus and I/O there.

But then, you couldn't have built short-length cards later.

I'd have to dig out my spec to see if those were even

NeXT pushed for the double-clock edge version of the bus.
I think block mode happened around then as well.
