I have a TK-50 with a tape stuck in it, it is malfunking :-) I thought I would put it on my workbench and power it up but that doesn't seem to leave it with enough smarts to load and eject tapes. Do I have to hook a TQK50 to it? (I suppose I could bolt a bit of Qbus to a board with power but I'd rather not if I don't have to.) Is there a jumper/testpoint I can change to put it into "local loop" mode? --Chuck
