Apollo is the classic example of using plain 68K (two).
I always associate it with Tandem:

Not sure what you are referring to, here. Tandem did not use 68K
processors as the main CPU
in any of their machines. (There could, possibly, have been 68Ks in
some of the peripherals.)
Yes, you are right. The report gives some examples of dual 68000's in
Tandem's peripheral subsystems.
I likely was thinking of Stratus, because I remember reading this before:
http://pages.cs.wisc.edu/~david/papers/ibmsj1987_stratus.pdf
Also Sequioa, who also used two 68000's operating in lockstep, described
in P.A. Bernstein's paper that is comprehensively paywalled :(

They had their own 16-bit mini architecture, loosely based on HP's stack
oriented minis.
