The LCG01 was the most unreliable and flaky color printer ever made. It
was a Tektronix print engine which sat on top of the LCGO1-CC rasterizer
unit and took print commands from it.
The LCG01-CC unit first downline-loaded its program from a host computer,
over a serial connection. Then it accepted print jobs in a number of
different formats including sixel, which it would render and send to the
Tektronix ink jet printer which would jam and then squirt ink all over the
person trying to unjam it.
As I recall, the unit has a PDP-11 instruction set inside the box.
Not very many of these things were sold because the complete system was
very expensive and didn't work very well.
