Ah, right.  I never had a personal need to run multiple WPS-8
stations, but, yeah.  I remember that.  That's probably where my KL8A
came from - a WPS-8 system in a 42" cabinet with two sets of floppies
and an -8/a in the bottom.

That would be amusing to set up, but I don't know that I'd want to
_use_ it for any length of time.
