Are you sure, Tim? My 11/73 doesn't, and according to my microPDP-11 Maintenance Manual, only the 11/23+ and microPDP-11/23 have TU58 -- the only tape devices listed for 11/73 and 11/83 are TK25 and TK50 (my manual is too old to include 11/53 and 11/93). -- Pete Peter Turnbull Dept. of Computer Science University of York
