I've only seen that work flawlessly on older Quantum and Micropolis discs.

Yes.

Unless my memory fails me, when looking at the system from the front,
the IDs are assigned like this:

    3    2
         1

It doesn't really matter, though, so long as you either set them all
manually or let them all auto-assign.  If you're paranoid, pick something
from 4 through 7, inclusive, since that won't conflict.  Keep in mind,
however, that the machine expects to boot from chain 0, device 1, unless
told otherwise.
