I worked at Lexitron in the early seventies.
The system I worked on was probably an earlier version as it didn't
look as modern as the one in the pictures.
I do remember the huge power supply to power all of the circuit boards
which were loaded with discrete chips like: and, or, nand, and nor
gates.
Ther printer was an IBM electric typewriter with a bank of solenoids
mounted above the keyboard.
No microprocessors here!
I'LL search my memorybanks to see if I can remember anything else.

  Hello all,
 I mailed about this last year, and got no response, so here again:
 I'm looking for info on this very strange terminal/wordprocessor from
 the early seventies:

 as you see, there is not much info on the web about this very beautiful,
 yet strange beast.
 Unfortunately the picture tube is broken and we are missing the main
 processing unit. It seems that the display used vector graphics as the
 horizontal an vertical are identical in design and the normal raster
 scanning generators are missing. the terminal connected with a 94 pin
 connector to the main unit, being also fed power though this cable.
 anyone
