CosmicDreamer hi,
My XV5080 came in an ordinal brown recycled paper box

with a manual, a reference cables but no demos CD or anything. The same about XV box. Roland distributor in my country (DIMITRIADIS S.A.) sent me an extra CD with SRX01,02 and some SRJV demos plus some S700 samples. The manuals also had many minor mistakes but maybe just because it was early made models. When they sent me (one month later) SRX cards their references was far better as well their package.
About R-bus cables: Yes it's true that there are some problems with some d-sub high density cable adapters but i tested a CableEye rbus cable with no problem. You can consult their site to find conversion solutions for use with Rolands, Tascam etc.
