Instant purchase OK! * Rust from battery leakage in the battery box (see image). * Keyboard tape in two places (see image). Operation confirmed, but I'm not sure how to use it, so I can't guarantee it's 100% functional. The touch panel works fine! I tried to check the printing, but it displayed "Specified ink ribbon not installed" and I couldn't confirm it. The LCD screen is in good condition for its age, with no burn-in. If you are knowledgeable or understand this, please purchase. I will try to answer inquiries about the product's condition as much as possible, but I am not an expert.
