EOPS Circuit

Here are some possible meanings. The first (Electronic Point of sale) is probably the one you're after.

Because you produced an anagram of the "EOPS", i.e. Electronic Point Of Sale, I will add my two pennies: ESOP (Employee Stock Ownership Plan), or, in some phonetic languages, the Greek fable author.

As for EOPS Circuit...never heard of it, but I am a bit deaf.

I picked EPOS because Guest spelled it that way within the post - I agree "EOPS" doesn't seem to register with anything most of us have ever heard of.

I guess the big question is: Was the Big Question "EOPS", "EPOS", "ESOP" ... (_{can't be bothered to type all 4! = 24 of 'em}) or what?

[BTW - I sometimes start a thread with a typo in the title - it's very embarrasing when you spot it, and seems to be totally un-redo-able ]
