PSP 1000. Operation confirmed. The power switch on the 1000 is chipped. The 1000 is functional, but it's an old product, so please consider it as junk. Charger, manual, box, etc. are not included. #kan5656 *No immediate purchase. Please comment before purchasing. I'm open to some price negotiation, but please keep it within reasonable bounds. If someone purchases without commenting, I may cancel the transaction and block them. If I don't receive a response to a comment within the day, I will consider the offer withdrawn.
