How have you cleaned the crud out of the cable?

Have you pulled the inner cable and checked its not snapped in the middle, and then greased?

Symptoms SOUND like simple case of snapped cable to me.

Speedo goes 'crazy' as the wire starts to break up & it twists and unwinds... then gives up altogether when it finally snaps.

Is the end rounded off? If it was fretting in the drive, then they can loose thier corners and 'jump' until they completely round off, similar symptoms.

Symptoms suggest cable. And 9/10 times speedo faults are the cable. I'd not be so quick to dismiss it.

Try finding something you can drive the speedo with off an electric drill.... I'll bet it works, and its the cable slipping.
