I remember the RM05 (CDC 9766) and the RP07, which I _thought_ was a 100% DEC design (that resembled a white washing machine with no access panels), but I could be wrong about that. My memory may be slipping. We had a 500 MB drive that fits the description, MASSBus only, and just a couple buttons on the front. You had to open the back to flip the circuit breaker off to reset the drive - which I had to do a LOT until they fixed some of the firmware bugs. I THOUGHT the model was RM07, but maybe it was an RP07. I thought RP was for removable disk packs, and the RM was for fixed HDAs. The drive we had was definitely made by Burroughs, it had Burroughs labels on the boards ons other parts inside. I gather it never was very popular due to price, and so I can't find much online. But, I did find one pic with a readable RP07 label and it looks like I remember. We never had to leave covers open on ours, and had no overheating problems, although the HDA did run hot enough to almost burn your hand! We did have under floor cold air supply in our machine room.
