  I pulled two RA70 disks from a pair of VAX-3500s that
I have. By some
 miracle both drives spin up and go ready when the Operator Control
 Panel is connected. I was thinking that one of these drives would work
 nicely with the UDA50 disk controller in the 11/44 until I can get the
 RA81s sorted out.

 These drives are supposed to work with the Operator Control Panel.
 There is a button on the back of the drive that says Unit Number
 Accept. I pushed the button both before and after power up, but the
 RA70 does not spin up.

 Anyone have a manual for this drive or know how to get it work without
 connecting an OCP? 
I have used RA7x drives with a KDA50 (M7164 / M7165) without an OCP
attached to the drives.  It has been a while now.  I don't remember
there being anything tricky about getting it to work.  I was probably
using either an RA72 or RA73.  I'll have to look and see if I have an
RA70 to try.

I don't remember if I ever found any RA7x drive manuals other than
this one on the net, which doesn't have all that much useful
information:
RA7x/SA7x Pocket Reference Guide, Order Number EK-RSA7X-PG-002
