Thank you for viewing. I purchased this on another flea market site, but the AC adapter is missing, so I cannot confirm its operation. I am listing it because of this. Since the details are unknown, I am selling it as junk. I am unsure if memory etc. are included. Please understand that there is a possibility that it may not work before purchasing. Please refrain from price negotiations. This product is junk, so I cannot guarantee its operation. NCNR (No Claim, No Return) is requested. Thank you.
