Somewhere in the back of my head I had the idea that a
TDP-100
was a Coco ... that Radio Shack could sell it as a color
video terminal.
They did sell a "VideoTex" terminal that sure looked like a coco. Sold
it
for use with CompuServe, (among others,) as I recall.
there are surely some in this crowd who remember the excitement over
VideoText back in the early 80's.
