I accept the challenge...

From "Logic Handbook", published in 1968:

 RANDOM ACCESS DISC

  A new DECdisc random access memory storage device significantly expands
  the memory capacity of the PDP-8/I, PDP-8, and PDP-8/S computers.  The
  DF32 has a capacity of 32,768 thirteen bit words (12 bits plus parity)
  with capability of expansion to 131,072 words.  It is a fixed disc with
  one head per track.  Transfer rate is 66 microseconds per 12 bit word.
  Average access time is 16.67 milliseconds.

Also described in the handbook, besides the PDP-8 machines mentioned above,
are the LINC-8, the PDP-9, and the PDP-10 (models 10, 20, 30, 40 and 50).
The rest of the handbook is a catalog of FLIP-CHIP modules!
