Running a TK50 "on the bench"

A properly functioning TK50 should be able to load and eject tapes even if not plugged into a controller. Can you rapidly switch in/out the red light/button for three or so cycles, with the final position being "out" (unload)? What happens when you try this? If *nothing* happens, then there's something seriously wrong (electrically) with this TK50. If it attempts to unload but doesn't quite do it, and ends up with the red button blinking rapidly, then there's probably a mechanical problem, most likely with one of the capstans or the corresponding optical interrupter. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
