Yes. The new DG4-2 and -8 replace the concept of the MCO. It's much easier
to work with too!

No. I think you'll find that your problem is that you need to "Edit
Globals" and make the total display size larger. For two 1280x1024 size
windows you'll need a total managed area of 2560x1024. (Assuming you have
the RM's to do this)

Yes it has. I believe the Onyx2, like the O2 - uses a PC type RS-232 pine
layout now.

No. It's just a matter of rewiring the cables. The sex has changed too I
think. Once you've got your cable right, you'll be fine. The good news is
that you can now use standard PC serial cables.
