I don't think so. As far as I've ever seen, only the 11/04, 11/24, and
11/44 have MUD slots, and they only have a few of them. It's only for
22-bit memory addressing. The 11/70 had a dedicated memory bus that wasn't
a Unibus variation. The J-11 based Unibus machines don't normally use
Unibus memory at all, let alone MUD.
