Check out the third-party companies; we had such a controller at my previous employer, but that was a very long time ago and I have forgotten who makes it. > >DEC RK07 If there is a DEC controller for this, it will only support 18-bit addressing. Depending on the O/S that you choose to run, and the type and amount of memory you have, this may be a problem. I have no idea about third parties, but I'd doubt it. > >DEC RL05 (I think) No such drive. If you mean RK05, the controller you want is an RKV11. Unfortunatly, this has only 18-bit addressing, so it might not be good for you. Again, I doubt that any third-party controllers would work. If you mean RL01 or RL02, than you are in good shape. The RLV12 controller will support them, and has 22-bit addressing. There is also the RLV11 varient; this one is 18-bit only, and I'm not sure if it supports the RL02.
