The entire assembly including the ribbon cables (which connect to the paddle board using soldered IDC endings rather than the usual Berg connectors) has another #, 54-class I think????? IIRC the reason it's different (besides the fact that the RK8E plugs into regular Omnibus slots and wouldn't be able to dedicate a backplane slot to the Unibus style cable that the RK11D uses) is that the RK8E uses the old individual drive select lines (for four drives max), not the new encoded drive selects (for eight drives). Could be remembering wrong though. Anyway this only matters between the controller and the first drive, after that you can connect the other drives using Unibus cables. John Wilson D Bit
