No, I have a vague memory that the 1010 is mostly the opposite,
only one receive and one transmit buffer at a time.

The same device existed for Nova, programmed in the same way.
Interlad had a small logic board that was glued onto either an Unibus or 
a DG I/O card.

I have programming manuals for both of them around somewhere.
