The RP06 was the successor to the RP04 and RP05 multi-platter large disk drives. The actual drive was a Memorex 677-01, OEM'd by DEC, who added interface electronics.
As a MASSBUS device, it did not have a specific device controller, but used the appropriate MASSBUS controller. A maximum of 8 drives were supported per controller; drives could be dual-ported, to allow access from two different controllers.
The block headers are protected by a CRC, and the data by an ECC.
