Yes. I never got a good look at the 370/135, but I'm pretty sure the disk subsystem on the 4341 was a 2- or maybe 4-drive 3033. I remember a power failure: the emergency head retract worked, but it jammed in the retracted position, and we had to get a technician out (from CDC!) to free it up before the system would IPL.
