Instrumentation and Controls:
Viewer system status [IC; Norris / McCaughan]
- Recable 2 viewers in keV whose channels & hardware were appropriated for HDice (done)
- Reconnect IYGM401 (formerly ITV, now YAG)
- Drag cable and connect IYGM603 and IYGM603 (appropriated from HDice line, swapped ITV > YAG).
- Brian Freeman available for adViewer work for video camera for ITVM604A? Dome focusing still required...
Wire Scanners [Delacruz / Poelker]
- IHAM703 Status (Scanner swapped out)
Chopper Controls (Windham/Lu)
- STAC5 Controls replacement (done)
- Encoder mapping (/10)
- Controls transparent to user
Chopper Controls (Windham/Lu)
