I once ran into a Siemens computer used to control a Contraves precision
drawing machine. I found recently that those were mainly used for drawing
master plots for printed maps. I remember nothing about it except that it used
hex digits 0-9, where 9 could also be written as A, and then B to G for the
digits representing 10 to 15. Does that ring any bells?
