I don't remember ever afixing H960s together - just cranking down the
feet so they didn't move. Newer racks (like the 42" corporate-style
cabs) _did_ have panels to lock racks together, but I think that was a
new thing in the early 1980s.

Ooh... can't help with something that processor specific, sorry. If I
had to guess, it'd be easier to have one or the other, not both. In
the case of semi-modern OSes, I wouldn't worry about core - it's
really nice when you are loading things from papertape and when you
are toggling bootstraps, but when you can press a switch to load fresh
from the boot disk, the non-volatility of core is less important.
