I doubt it. At a time when electronics was shrinking rapidly, a compact unit, giving the impression of advanced technology, would probably have been far more effective. That case looks very generic to me, so it was probably more about cost/sourcing than anything else.
Probably a hard concept for you to grasp, but not everything is about flimflam you know. ;op
