Sounds like you have the Floppy Cable backwards. Try plugging it in the other way around. You have Pin 1 and pin 40 flipped. A constant light and spinning motor is the usual symptom of that. Another way to get data off that machine is to use LapLink V and a Serial LapLink Cable. There were several work-alikes to LapLink like FastMove and others. You should be able to buy LapLink cables rather cheaply these days.

I've been looking through the stash, and so far I haven't found anything. Second, IIRC the speed and "low density" recording current are set with jumpers. What is the etc.? I might add that when connecting a standard 360K drive, the light comes on and stays on, and the drive continues to spin when a disk is inserted. This gives me the impression that there may be something wrong with the disk controller for the Tandy 2000. The cables for the 2000 are straight-thru, so I rejumpered the drive to the first drive (D0 of 0-3 or D1 of 1-4.) And yes, I checked and double checked to make sure that pin 1 on the motherboard matches pin 1 on the drive! Thanks!
