In looking at the RK07 and RL01/02 drives that I have from the Great Haul, the connectors and cables look rather similar. In the 11/34A I am keeping, there is a five-board set which is the RK611 controller. The previous owner had RK07's hung off this controller. I want to use at least one RL02 in the system as most of the disk packs with the important s/w are RL01/02. Anybody know if the RLs will work off the RK611 controller? (This is one of those dumb newbie questions!) If it won't work, anybody have a spare RL11 controller module (M7762) they'll let go? There's a heap of RL's (7) in the stuff I got but the only machine in the whole pile that has an RL11 is the 11/24 which is not going to be kept by me. What would the cable run limits be on either the RL11 or RK611 systems? As someone had told me a bit earlier about SDI systems, only ODD number of cables must be used. Any such limitation here?
