Thanks for your input.  :)

1.  No stick shaker stall warning when stall test is activated and no stick shaker sound prior to stall.
Did this 727 setup actually have stick shakers?
Ok, just looked it up in the manuals, you are right of course.

Quote:

The stall warning system components are as follows: an angle of airflow sensor, a flap position transmitter, a stall warning computer,  a control column  shaker motor and a  landing gear safety  (oleo "squat") switch circuit.

2.  No takeoff config warning horn.
Did it have this item? The 707 did though and I couldn't make it work there (have to add this to the list, I guess).

3.  No landing gear config warning horn (might be there but I don't recall).
Can't remember hearing it too, but there's a cutout lever, so it should be there.
