 From article <13001@accuvax.nwu.edu>, by radar@cd.chalmers.se:

> When and by whom was the 19" rack standard invented ?

As this is a telecom newsgroup, I feel compelled to mention that AT&T
equipment racks [5ESS(Tm)] are usually 22.5" wide. NTI racks can be
24" or 44" (?) wide. [These are the widths of the card cages, overall
width is somewhat larger.]

"The best thing about standards is that there are so many of them."
