You can use your 3583 by redefining it as a manual library.
Edit the devconfig file and redefine the library as manual - you will also
need to delete all the drive definitions except for one.  Then use tapeutil
to move the db tapes between the IO slots and the drive.
eg:  DEFINE LIBRARY LIB_NAME LIBTYPE=MANUAL
     DEFINE DRIVE LIB_NAME DRIVE_NAME DEVICE=/dev/rmt0 ONLINE=Yes
