This is a SHARP pocket computer, likely manufactured in the 1980s. It features kanji input and can be used for learning BASIC programming, as well as a scientific calculator. I have confirmed that it can perform basic calculations and program creation, and that inputting, calculating, and displaying characters works without issue. However, I have not confirmed all functions. Two expansion RAM cards are installed on the back of the main unit, achieving a maximum program capacity of approximately 64KB for this model. The exterior has minor scratches, dirt, and paint peeling. Please check the photos for details on the condition. There is no cover or instruction manual for the main unit. Regarding the 128KB RAM CARD: A prototype self-made RAM CARD is included with this item. On the PC-1360, one card can increase the program capacity by 32KB, and it backs up programs independently using its built-in battery. On models like the PC-E500, it can increase the program capacity by 128KB. Since it is not a genuine product, long-term stability is unknown.
