- * Type B Past Week Summary
  * Mark and Hirata-san at Mitaka
   * Gathered parts for cable making.
  * Mark and Hirata-san at Kamioka:
   * Replaced the floor panels that had been taken from the PR2 area (filling in the hole in the floor) and found/installed two new panels to act as bridges near the BS assembly frame.
   * Installed two more LPCDs and the stepper motor driver in the PR2 rack.
   * Ran cables from the rack to the second and third sat amps (for the IRM OSEMs).
   * Added a second DIO card in the rack and connected it to the BIO inputs and outputs of the new LPCDs.
   * Started making extension cables for RM-H2 and -H3 OSEMs but gave up due to complicated grounding arrangement. 
   * Washed four 40-cm D-Sub-9 ribbon cables to use as temporary extensions (maybe also for H1/H4).
   * Added extension to the IM pico cable for the BF yaw pico.
   * Made LVDT adapter cable.
  * Mark worked on schedule.
