Thank you for viewing. SHARP Statistical Pack II CE-12A3 for PC-1250/1251 - 1 tape This appears to be a tape containing programs for Sharp's old pocket computers, but please forgive me if I am mistaken. Please refer to the ruler in the photo for the size. The instruction manual has 26 pages. The box has scratches, marks, dirt, and residue from a price tag. The tape is unopened with its original plastic wrapping, but due to long-term storage, I cannot guarantee that it will work properly. Please consider it as a collector's item. There is no guarantee of operation. If you understand and accept this, please purchase it.
