- Make a new OPOS_MASTER.
- Change top-level of h1susopo.mdl
    - Delete VOPO library part
    - Copy over OPOS_MASTER model part, rename to OPO
    - PCIe tags: ISC_2_VOPO > ISC_2_OPO
          (Don't forget to rename channels *inside* the bus creator, and reselect on the bus selector side)
    - Binary IO tags: DIO_2_VOPO > DIO_2_OPO, VOPO_2_DIO > OPO_2_DIO
    - DAC Tag: VOPO_2_DAC > OPO_2_DAC
    - Make sure ADC input to OPOS block ordering map is
          ADC_1_28 = H1
          ADC_1_30 = H2
          ADC_0_18 = H3
          ADC_1_29 = V1
          ADC_1_31 = V2
          ADC_0_19 = V3
    - Make sure OPOS block to DAC output ordering map is
          H1 = DAC_6_08
          V1 = DAC_6_09
          H2 = DAC_6_10
          V2 = DAC_6_11
          H3 = DAC_6_12
          V3 = DAC_6_13
          (Do so by re-ordering the bus selector coming out of the OPO_2_DAC tag)
- Save and Compile
- Bring OFI, ZM2, ZM1 to safe (either by guardian or by hand)
- Check H1SUSOPO sdf system to make sure you've accepted everything that you've done so far
- Install and restart model
- DAQ restart
- Update SITEMAP to point to susopo_overview_macro.txt 
- in sus/common/medm/
    - cp susvopo_overview_macro.txt susopo_overview_macro.txt
    - svn add susopo_overview_macro.txt
    - svn commit -m "" susopo_overview_macro.txt
    - svn mv vopo opos
    - svn commit -m "Name change from VOPO to OPO" 
- in sus/common/medm/opos
    - svn mv all files from *VOPO* to *OPOS* (painfully, file-by-file)
- Update macro file
    - OPTIC: VOPO > OPO, optic: vopo > opo, INSTANCE: VOPO > OPO
    - updated ADC / DAC outputs
    - Added SUSTYPE=OPOS and sustype=opos
- Update OPOS_OVERVIEW.adl and associated subscreens
    - Search and replace VOPO > OPOS in call to sub screens
    - Change OSEM2CART to OSEM2EUL
    - Change CART2OSEM to EUL2OSEM
    - Reorder H1V1H2V2H3V3 to H1H2H3V1V2V3
    - Rename all X Y RZ Z RX RY to L T V R P Y
    - Add new RMSLP to the watchdog screen
    - fixed some subscreen lines
- Filled in *some* infrastructure with OSEM2EUL and EUL2OSEM matrices from TST aLOG 11396
    https://alog.ligo-la.caltech.edu/TST/index.php?callRep=11396
- Filled in OSEMINF and COILOUT filter banks with standard HAM-A driver + US SatAmp filtering
