More interesting TK50 fun - test-drb@ccmp.vtda.org

...
 So several questions come to mind. I'll pop out
some of the obvious ones...

1) Does the Red Light/Button on the right hand side in the "out" position 
mean "unload" ? 
Yes.

...
 2) When does the green light come on (except on power
up when it is 
unloaded.) ? 
Green light on (solid) means it's OK to operate the handle.

...
 3) It appears that a "working" unload
sequence would have the tape leader 
get sucked back
    into the tape and the 'unhooker' should engage the hook leader. Why 
would it stop
    before it got that far? 
While it's doing its tricks, look carefully at the metal capstan that
the tape and leader goes over at the rear of the drive.  There's an
optical interrupter connected to the shaft of this, and this is the
only way that the TK50 knows that the tape is actually moving.  If tape
or leader is moving over this capstan without turning the capstan, the
TK50 drive gets all confused and gives up.  So look carefully to see
if that capstan is turning as tape gets pulled over it.
