InCider published plans in '84/'85, in the early days they actually had 
HARDWARE construction articles.  They used a tri-color LED to indicate
the various states, so no extra drilling in the case was required, although
the hardware to drive the LED may have been a bit more involved than with
the more 'modern' two-element LED's. (3 wires, 1 Red, 1 Green element)
