We are using a TK70 under RSTS without any software problems (conf: J11 CPU, 2xRA80, 4xRK07, TK70, RX33, 2M, RSTS V9.4). No tricks, just mount it as MU?:. (You first have to specify its controller while monitor generation, of course) The only problems which may occur are about reliability. I've tested 3 drives and it seems to be a feature that TK70's often kick the bucket if they are close to the upper temperature limit (happens during system installation/update because FIP is winding the tape almost the whole time). For cassette streamers, they are VERY slow (up to 30 min for file lookup).
