I suspect that this note was taken in jest, however, it is true that color CRT's are highly sensitive to the earth's magnetic field and at the equator such sets must face north or south to be in line with the horizontal field. Color sets do not work properly when rotated. The suggestion that you investigate this on your own CRT by inverting it is sincere. Sorry if I misinterpreted dry humor but there was an unnerving tone of disbelief in the postings. jobst_brandt@hplabs.hp.com
