Now I'm looking at a different system which claims to be a //c+ but with an _external_ power supply. The model number is given as (sic) A254500 ... probably A2S4500. Does that sounds like a //c+ model number despite the external power supply?
The Apple //c+ has an internal power supply - any external PS would likely be included by mistake, or a power converter/conditioner for overseas use. I've seen a couple of those (rarely).
