No photo of the Dacta interface box...
Oh the joys of lego dacta. Programming light sensors (that could tell the colour of bricks), motors, conveyor belts, and pneumatic systems - although the latter I seem to remember was manual, not programable)
I'm surprised there is no mention of the old LEGO Technics Dacta interface box:

You plugged all the sensors and motors in to this and connected it your computer. Many a times I remember hitting the big red stop button as my creations went haywire or were about to commit some act of self destruction.
Worthy of a photo in the article me thinks - although that might just me being nostalgic: I'm pretty sure this box of tricks and my teachers enthusiasm is what sent me on a career of application development and delivery.
