Keep in mind, these things were in vogue back in the days when the *users*
actually *expected* to get the schematics! My how times have changed . . .

The Z-67 is a rare item indeed. I missed one in 1988. That's the last time
I ever saw one offered for sale (and it was *just the interface*). I don't
know anybody running one of these . . .

My Z-89 dosen't run anymore. Too many years of disuse, I guess.
