Swiss Micros makes HP 'act-alikes' - programmable

[Thomas Okken]

It could be that XEQ makes more phonetic sense to Americans than to people from the UK. I couldn't say. As I said, English is not my first language, and my language sensibilities have been heavily influenced by living in the U.S. for some 18 years. On the other hand, I bought my first HP-41C back in 1979, when I had started learning English just a couple of years earlier, and I "got" XEQ right away. Maybe it's just random, like whether you like jazz or not.

Interpreting XEQ as "not EQ" wouldn't have occurred to me. The opposite of EQ is NE.
