It always had 10 buses actually, timings have not changed. Perm
buses for 911 are SMB128B, SMB134H, TIB756K, TIB757H, TIB1032J,
TIB1039R, TIB1047S, TIB1139K and TIB1170T. The problem is that
911S150 has no perm bus so it isn't recorded in SGWiki...
duties are 911S101, 911S102 , 911S150, 911S201, 911A/P01 -
