$0B

Command error (bad command code, bad timing, or command

2

 

door was closed when a command was received) = 00. Custom

 

 

SCSI sequence: controller level not equal to "147 local level", or

 

 

interrupt not on. Format: format with defects on a con- troller type

 

 

not supported. Controller reset: controller not SCSI type. Space

 

 

(tape): undefined mode. Mode select (tape): undefined controller

 

 

type. Mode sense (tape): undefined controller type.
