Filed: 1983-05-25
Abstract: PURPOSE:To unify the device type information for a magnetic disk subsystem by making use of an unused byte of the information to a sense instruction to report the device type information to a host device. CONSTITUTION:A magnetic disk controller 2 receives an instruction from a channel 1 of a host device and decodes it to decide whether it is a sense instruction or not. If no sense instruction is decided, the instructions other than the sense instruction are processd to complete the operation.
