### <a id="other">Other differences</a>
- usage of 11/70 SYSID register
- in real 11/70's sysid held the individual serial number
- in the w11 project sysid encodes the execution environment
- this allows to distinguish between real w11 and emulation under SimH or e11
- the SYSID is divided in fields
- bit 15: emulator flag (0=w11,1=emulator)
- bit 14:12: type, encodes w11 or emulator type
- bit 11:09: cpu number on 11/74 systems
- bit 8:0: serial number
- current assignments are
- w11a: 010123
- SimH: 110234
