Subject: SUMMARY: Local-and Ethertalk same time (A)
Date: Wed, 18 Aug 1993 10:29:13 -0400 (EDT)

It turns out that the solution for us is to use our existing
GatorBox, and let the GatorBox route to the printer.  I can't
tell if it's slower.  We won't be re-wiring, so if the GatorBox
does go out, we can always go back to switching the interface.
