[Coco] Useless but rare...

Weird - almost like a precursor of the CoCo 1!

Did Percom have any relation or input (via employees if nothing else?) 
to the CoCo 1?

It seems that this "method" of a "second" screen for some extra 
graphical means is common in the computing world, even today.

First it was oscilloscopes (with teletypes).

Then it was graphical screens (vector or raster) with character terminals.

Then it was high-resolution mono graphical screens (hercules) with 
low-res color (ok, maybe this one is a stretch).

Today? Not really sure; one could argue various 3D volumetric displays, 
or maybe HMDs, CAVEs, etc. In a manner, one could even say 3D printers 
are such a "display" (just a very slow one) - again, a stretch (ok, 
maybe that broke the analogy).
