Rare - your command of the Written Word is certainly skewed. You must be in sales, marketing, or politics.
At best MMr is a Coin-OP Capable machine. It is not a coin op machine as it requires a retrofit of a pair $16 coin mechs for it to be a coin-op machine. Both terms are 100% correct; don't go "playing with the words" because you think you can "justify" your insistence that it is a coin op machine. It simply isn't until someone retrofits said coinmechs in place. If MMr's brochures or any other marketing documentation claims itself to be a coin op machine... then well; they are putting themselves up for a false advertising claim.
"Coin operated" is defined as:
1. operated by inserting coins in a slot.
2. noun: coin-operated; plural noun: coin-operateds; noun: coin-op; plural noun: coin-ops
a machine that is coin-operated.
Retrofit is defined as:
verb: retrofit; 3rd person present: retrofits; past tense: retrofitted; past participle: retrofitted; gerund or present participle: retrofitting
1) add (a component or accessory) to something that did not have it when manufactured.
"drivers who retrofit catalysts to older cars"
2) provide (something) with a component or accessory not fitted to it during manufacture.
"buses have been retrofitted with easy-access features"
noun: retrofit; plural noun: retrofits
an act of adding a component or accessory to something that did not have it when manufactured.
So; It is 100% point blank accurate to say MMr is not a coin-operated machine and that it requires a retrofit of the coin-mechs at additional costs to make it so. Further; Just because you can retrofit the mechs into the machine makes not guarantee that said machine will function as a coin-op machine. I doubt your buddies at PPS are planning on testing all the features of said coin-op machine on a per-unit basis... so it's possible you as the new owner of your non-coin-op machine will have to fight with PPS to get it repaired under warranty.
Whatever the case; I'm done "sparing" with you over the English language. Your "facts" are certainly a waste of time.
