Well, I was referring to the rules about how to assign CSRs in the floating space. Assigning them in the floating space is what confuses me. ;) But yes, for those devices that have a fixed address for the first one, the first one is easy. :-) (DHVs do not have a fixed address.) What threw me off was that the DHV11's address in the manual was 22-bit and SYSGEN wanted 18-bit. ;) (By the way, congrats on getting the machine running.) Thanks! I got RSX-11M+ 4.6 on it and I'm doing a SYSGEN there now. 4.6 will be better than 4.3. I'm fine with half a board less RAM so long as it WORKS. Indeed. And 4.6 is better than 4.3 Yup. I even copied the pre-made baseline image so I could get the networking bits easily. They're on DU2. Johnny -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects
