VAX 11/780 to 785 upgrade, what does it take?

Hello, I know some of you are former VAX field service technicians or have other deep working knowledge of this: what exactly (!) does it take to upgrade a VAX 11/780 to a VAX 11/785 (or 11/780-5 as it was called.) I believe this includes changing the SBI backplane. But what else does it include? Is the console computer any different? Power supply? As you probably all know, I have the 11/785 board set on hand but no cabinet. Now I have the chance of transporting one or two 11/780 accross the country. Those are in real good shape as I gather (were stored inside!) So I figure I rather have a nice 11/780 than a rusty incomplete 11/785 that lacks a console computer. And with some chance I can upgrade one to an 11/780-5. So, what does it take? thanks for your advice, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org
