Ummm.  The best I can find is:

     ___________________________________________________________________
  2.3.7 Cryptographic Facility

   Depending on the model, an integrated cryptographic facility may be
   provided as an extension of the CPU. When the cryptographic facility is
   provided on a CPU, it functions as an integral part of that CPU. A
   summary of the benefits of the cryptographic facility is given on page
   1.3; the facility is otherwise not described.

And, irritatingly the "Hardware" link on:

   Linkname: IBM: z/OS Internet Library - Technical documentation and
          literature for the z/OS platform
        URL: http://www-1.ibm.com/servers/eserver/zseries/zos/bkserv/

... takes me to S/390 hardware.
