2. Upgrade (CAMAC) DAQ upgrade influenced SCS:
Old hardware was removed and replaced by custom built boards
TOF CAMAC crates with CFDs are gone
TOF TRB boards are now used by DAQ to set thresholds
No more CAMAC needed
Burkhard Kolb GSI

3. Upgrade (VME) VME crates with CPUs for readout are gone
Replaced by TRB boards
Wiener VME crate control not needed any more
Power control for TRBs by TDK/Lambda power supplies
Power distribution boards
Burkhard Kolb GSI

4. Upgrade (CTS) The VULOM board (VME) was removed
Now with more functionality in CTS board
Replaces most of the trigger logic
Replaces the scalers for beam and triggers
Control via EPICS IOC and trbcmd server
Needs some work to write daq compatible script files

8. Software upgrades For RPC the MEDM GUI is replaced by CSS
Archiver and data server updated
Trending data can be seen in CSS
CANbus control moved from VME to HADcons
More sequencers are built for unattended operation

9. Conclusion Hardware is constantly changed
Abstraction and system approach helps
Software (EPICS) framework stays
Backward compatible to oldest parts
New GUI concepts (CSS) fit seamlessly
Provides new functionality (trending)
Need manpower to convert all old MEDM screens to CSS
Alarm handling in CSS needs some work
