Well, yeah, I realize all that. What I'm saying is that I saw a diagram that
displays connecting the dials device via BOTH the tablet and RS-232 ports,
i.e., you may not be able to do a full daisy chain for everything via the
tablet port alone.
What I found was a couple pages out of the Adapters, Devices and Cable Info
for MCA-Bus Systems book. It shows some connection diagrams, but they take
into account the LPFK (Lighted Programmable Function Keyboard). May not be
of any help here yet, but at least I found what I remembered reading about
the dials device in.....
BTW, what is an IBM RT PC? Anything at all related to RS/6K's?
