Unibus UDA50 pinout, qbus RL02

Hi, Does someone have the pinout for a UDA50 ? I have the two-board-set M7485-YA and M7486 but I don't have the cables and I know about the "uneven number of cables"-rule. Currently the RA80 has two cables connected to the cabinet (mini bulkhead?), from there's another cable haning loose. Can I make a cable that fits onto this cable and the UDA50 ? What kind of coaxial cable should I use ? Anything else I should know or check before powering up the drive ? Another topic: M8061 (qbus, RLV12 for RL02) Something strage is happening when I try to boot from or access my RL02.... Configuration: PDP 11/83, 4mb ram M8061 and one RL02 (drive0), terminator When I boot the RL02, the run light simply goes off. No error message, nothing. the clock signal from the controller should be there, because i can load the disk, the drive spins up and the Ready "0" light goes on. When booting 2.11BSD (from RD54) the same thing happens: the run light goes off, again no error message. The loaded diskpack contains afaik no usefull information. Trying another diskpack didn't change anything. The controller is jumpered as described in the RLV Users Guide and set for Q22 operation. The drive & cable are ok, because I can hang it on my 11/44 and boot RSX11M from another diskpack with it. Thanks, lothar.
