Yesterday I asked some questions about adding a Xylogics 7053 disk controller
to a Sun 3/160. Specifically, I was interested in whether or not a patch
tape was necessary for SunOS 4.0.1, and if the controller could reside in
slots 10-12 which have a common P2 bus. The answer is yes to both questions.
