I have a (no longer functional, unfortunately) BA-11 full of core for an
11/20 -- I guess you could say it has a Unibus interface....  :-)

I also have another third-party chassis (about the size of an RL-02 or
RK-05) full of static RAM with a Unibus interface.....  :-)

Seriously there's a researcher somewhere in the depths of IBM who's
worked out a way to print core at semi-conductor sizes and IIRC in three
dimensions.  His densities even in the lab are, IIRC, up beyond current
moving-platter disks.  I imagine once they get ready to mass-market
those things you'll find some with SCSI interfaces, though I'll bet
firewire will be the most common (assuming they make it to market while
firewire is still in vogue :-).  I can try to dig up some references if
anyone's interested.... (and can't find them on their own).
