All items are as listed above. The DUO-R main unit has been lens cleaned, pickup adjusted, partially solder repaired, and gear greased. The backup capacitor has been replaced. (5.5v 0.047f → 5.5v 1.0f) ※ The HuCard slot cover is missing. ※ The backup capacitor (super capacitor) is for save data power. It has been replaced with a new one with a larger capacity than the original. ※ Due to the original specifications, save data may be lost if the power is not turned on for a long period. To preserve save data, turn on the power for a few minutes every month. The data retention period is considerably longer than the original. The controller has been maintained using anhydrous ethanol and contact spray on the internal terminal parts. [Description of Bonus Items] The software has been tested for initial operation. There are scratches and other damage. The AC adapter cord is twisted. ※ The insulation of the base of the adapter was broken, so it has been repaired using heat shrink tubing. (Only the insulation is damaged. The internal wires are not broken.) Operation has been confirmed. The AV cable has been tested and works, but the contact is slightly poor. If it doesn't work well, adjusting the plug slightly should make it work. ※ The AC adapter and AV cable are included as bonus items as junk items due to the above conditions. ※ The bonus items are only bonus items, so there is no operational guarantee after purchase, and no compensation, returns, or refunds will be provided even if there is damage not mentioned. ※ There is a possibility that the system may not start depending on the condition of the software you own. ※ This is a maintained product, but it is a very old product, so there is no operational guarantee after purchase.
