Thank you for viewing. This is a PC Engine DUO that has been serviced (fully maintained), including replacement of the main unit's electrolytic capacitors and adjustment of the optical pickup. Both HuCards and CD-ROMs operate smoothly. Furthermore, analog RGB output has been added, and a double-shielded SCART cable is included so that it can be connected to an RGB to HDMI scan converter for retro game consoles. Images from gameplay are included. These were captured using an HDMI capture device for game streaming. I am looking for immediate purchase, and due to the nature of the product, I am unable to accommodate price negotiations. Thank you for your understanding. [Included Items] ・PC Engine DUO main unit (serviced, RGB output added) ・Original game controller ・Original AC adapter ・Original AV cable ・Double-shielded SCART cable [Operation Check] ・HuCard, CD-ROM operation ⭕️ ・AV/HDMI video output ⭕️ ・Audio output (volume OK, left/right balance OK, no noise) ⭕️ ・Headphone output (volume adjustment OK) ⭕️ ・Game controller button operation ⭕️ ・Save function ⭕️ [Condition Notes] Including the accessories, it is in good condition with few scratches for its age, and I think it can be called a beautiful item. I recommend it to those who will take good care of it. [Maintenance Details] We have brought together the know-how for maintaining retro PCs and game consoles over many years. ・Disassembly and cleaning of the main unit ・Replacement of all electrolytic capacitors on the main unit's circuit board ・Repair of deteriorated parts on the main unit's circuit board ・Circuit board cleaning with isopropyl alcohol ・Replacement of the save data backup battery with a new one ・Disassembly, cleaning, and greasing of the moving parts of the CD-ROM drive ・CD-ROM drive focus/gain adjustment Considering that the lifespan of internal components is about 10 years at the shortest, maintenance is essential to continue using it now, 30 years after its release. I think you can play it for 5 or 6 years, not just 2 or 3 years. Thank you for your consideration. #Yokomumu's PC Engine DUO Maintenance #RGB Output Added PC Engine DUO #PC Engine DUO
