ABSTRACT:
A selectible computer tape drive activation and deactivation technique apparatus is disclosed. The invention integrates with existing floppy controllers in a manner which allows activation and deactivation of a computer tape drive without the need for select lines. The invention programs the floppy controller so as to generate an activation command which may be appended by an address to specify the specific drive involved. Both the command and the argument are chosen to be consistent with existing Quarter Inch Committee standards. With respect to the deselect method, additionally a failsafe, independent deactivation path exists to turn off the tape drive in the event any conflict in drive operations were to exist.
