PDP-11/03 basic questions - some answers found.

I still can't find a schematic for the power supply, although I hope it's similar to the H780. But I did manage to unearth the PDP-11 "Field Guide" (thanks to Megan Gentry for maintaining it). So now I know my 11/03-L system has: M8189 = KDF11-B: LSI-11/23+ CPU Clearpoint 2 Mb memory M8061 = RLV12: an RL01/RL02 controller M7957 = DZV11-M: 4 serial ports M8053 = DMV11: V.35 Controller .... what's that for? A modem? Dilog CQ1610: 16 serial ports M8029 = RXV21: an RX02 controller. The RL02 was filthy on the outside but nice and clean on the inside, and powers up. Guess it's time to make a cable to hook it to the RLV12 and see if the Fault light goes off (just like my 8/A I assume). Although I suppose I shouldn't complain, how much trouble would it be for the institutions discarding hardware to disconnect the cables instead of cutting them off! Now all I need is some kind of OS on an RL02 pack, and a room full of twenty terminals :) -Charles
