- PC crt replacements

- Ben's End rack drawings. Updated? What changed?

- conlog of pzt steering mirror bias voltages.

- frame logging / trending of pzt steering mirror readbacks.

- LSC front end cpu starts to creep up towards 61 usec.
  16 Hz and harmonics appear everywhere.

- We need Rolf to protect the front end code against NaNs from ezcademod
and we need to prevent ezcademod from spitting out NaNs
(and find out what causes it to do so in the first place).

- linux and sun printing to new OKI printer

- More new RFPDs (4).

- Vacuum EPICS screen: TP on/off logic; TP readout; 
- EPICS state code for reading out TP3,
  and for protecting/closing V1 if TP1 starts to fail.

- suspension diagonalization & gain optimization

- Mode cleaner length monitor - not working?

- Fast DAQ signals from 1Y2.

- OSEM sensor glitches: still have them?

- ISS still saturating regularly?

- MC WFS gain and UGF was turned way down.
  How to get it back up?

- L7 mixer chip for MZ servo - when Osamu is ready.

- Linux framebuilder?

- ALH - ball is in my court to review all channels and settings.

- ASC implementation, including 33 MHz WFSs

Other things, not directly related to controls:

- beamline as-built documentation

- ISS pickoff after MC

- FSS pickoff before PMC

- DC photodiode thermal and noise performance

- TTFSS
