With the internal drive connected it will not boot. Beeps but theres garbage on the screen.
With the internal drive removed it starts up, returns the "Unable to find a disk online" message and drops to Applessoft.
With a 3.5" external drive connected but no disk inserted it does the same.
With a disk inserted it doesn't start up (garbage on screen)
With a 5.25" drive connected it starts, and boots normally.
I'm shuddering at the prospect, but would this be an IWM chip failure, or could it be something else?
