PDP-11/34a - RL02 Help

Hello List: I have some interlinked questions for the Assembled Gurus: I am trying to understand device adressing in the system as a whole.. is there a good 'base/vector addr for dummies' document I could be pointed at? I have looked (sunsite, etc) and I'm still missing something. I *did* find out how to find the backplane jumper to be removed when installing the RL11... after I discovered it, I notice some kind soul put a red sleeve on the CA1 pin on each of the slots.... Am I correct to assume that RL02s and RK05s can coexist and co-operate in the same system? I am trying to construct a 'fully loaded' PDP11 system, and I want to have the entire range of peripherals available, so that I can perform media and format conversion, as well as have fun running the thing. Will one system support the RX02, 9trk, RL02, RK05, DECTAPE, Paper Tape, consoles and a few terminals, and maybe an Ethernet adapter? I realize this will take a one or two expansion chassis... but am I getting overly ambitious for one CPU? Should there be, maybe, two closely-coupled '11s sharing the load? Eventually I am aiming for a VAX 11/750. Would it be 'better' to wait and use it's resources, whatever they might be? I want to spend a little less time maintaining and a little more time computing... and I'm dying to run some of the DECUS stuff on my Machine. Thanks So Much (in advance) Cheers John
