This is a dinosaur encyclopedia computer. It was used two or three times and then stored in its box. Operation has been confirmed. The condition appears to be good from a layman's perspective, but please consider it as a used item. It seems to have various functions, but I mostly only played the dinosaur battle game. The instruction manual is also unopened. - Brand: SEGA - Accessories: Instruction manual - Features: Dinosaur-designed buttons - Type: Educational computer - Language: Japanese Thank you for viewing.
