Five PDP-11 Questions

Hello list: Going back on-topic from the recent wave of off-topic posts (that is, assuming people consider the PDP-11 both classic and on-topic), I have five PDP-11 questions which I wish to post to the list. 1. Is the bootstrap for the MRV11-D (the MXV11-BF boot ROMs apparently) "conversational" or "automatic." Conversational being defined as similar to the BDV11's bootstrap, automatic being, you hit the boot toggle and the system automatically brings up a <device>. 2. Is there a 22-bit QBUS bus terminator board? (I.e. only a 22-bit terminator, no bootstrap/ROM, no DMA refresh, et cetera.) If there is what is it's name? 3. Somewhat tying into the above, but; is there a 22-bit version of the BDV11 bootstrap ROM/bus terminator board? Because personally I'd rather deal with a single quad-wide board I've dealt with before, then deal with a pair of boards I've never even *SEEN* before. 4. This is more an opinion question but... Would trading a KDJ11-BF (yes, -BF; it has an FPU) for a KDJ11-AC (or -AB with FPU; FPU required because it took me long enough to get a J-11 with an FPJ11-AA, I'm going to run my '11/73 with an FPU if it kills me), a MRV11-D/terminator or 22-bit BDV11, and a DLV11-J be a good trade? (More on this question later...) 5. What size of wire, and wirewrap tool is the one most best usable when dealing with the jumpers (and possibly backplane) of a DEC system? (Specifically, in this case, wirewrap jumpers on various PDP-11 option boards). In terms of my question number four; I ask of that trade because I have a KDJ11-BF and an H9275-A backplane (that's the Q22/Q22 serpentine 9x4 one), as I'm in the process of replacing my PDP-11 system. And -- natrually -- the -BF (being PMI) won't play nice in the H9275-A. So I would like a trade for a functionally similar set of devices in this case a KDJ11-AC (or -AB with FPU; read my FPU statement), some form of bootstrap, and a SLU (the bus terminator would be nice as I plan on filling up said H9275-A). Thank you, any who respond, Christian G.
