Emax

Two lights at the bottom of the row indicate BAD FLOPPY  DRIVE / DRIVE
disconnected / misconnected.
If you have a floppy drive that cannot be set DS0, this will also show the
2 lights....
Since you had it hooked backwards, it is also possible you blew out the
floppy drive control circuit on the Emax.

But that doesn't explain the display itself.
It is also possible that your display has gone bad...

My experience is that a bad connection to EPROM or the display connector
itself can result in this behavior of the display.

Basically- it is my opinion that you have multiple issues, not just one
issue resulting in the behavior.

If you have another working emax (1 or 2), you could try the display on it
without causing any harm.
If display works elsewheres, then now you are back to logic board having
the issue.
Same could be said of floppy drive- try it elsewheres if possible.
