  Hi all,

 I would like to connect a Plessey disk drive to a PDP11 RK11-D controller.

 The drive has a fixed platter and a removable platter, compatible to RK05  I 
...
  believe, and these numbers on it:
 Plessey 3468-0231
 PMDD/11B
 700540-200217D  

   If this is the one I'm thinking you have, it is more like an RL02, 
 RK05s are front-loading.  This is the "take the bottom off the 
 pack, put it on the spindle, and put the bottom over the top of the 
 pack" type...  no?

        No, it is not, this _IS_ the front loading type. But I would believe 
tat if Plessey
        made several versions, they all might be rather similar as far as the 
interface
        is concerned.

   If so, I belive I have the service docs on it...  must wait to get
 home tonite to see for sure.  I gave a PDP 11/04 system to a
 Listmember which had a pair of these attached.  I have written him
 offering copies of these dosc but so far only silence has returned to
 me..... 

    HINT HINT you know who you are.

   Anyway..

 Question: Would anyone have a maintenance manual for the Plessey drive 
 available ? Short of that, maybe the pinout of the connector, so that I  can 
...
  make the cable ?  

   I can copy this as well for any others with the drive in
 question...  let me know.  I will post the exact model the docs are
 for this evening. 

   Cheers

 John

If there is any relationship between the model you talk about and the model I 
have, 
I would certainly appreciate a copy !
