Tandy 1000 drive works but no index pulse, reads random noise
#6
Is the behavior I describe expected in that case? The drive spins and the head steps exactly when expected (and sits quiet when not in use), I just don't seem to get any data *back* from it.

Given that the motor already runs when needed afaict (listening) I'm not sure what other jumpers would be necessary besides the "In Use" and "Drive Select 0". I don't think the drives were anything special. For example, http://www.oldskool.org/guides/tvdog/1kfaq.html#II.C.5 says:

> The original 1000, A, HD, EX, SX, and SL use standard 360k floppy drives.

That said, is there likely to be any harm in playing around with one or both of the HM/HS jumpers? A non-spinning spindle motor could certainly explain the symptoms (though not the noises) that I get when trying to image.
