I have tested the basic functionality of the CD-ROM2 software, music CDs, and Hu-CARDS I have on hand. Please understand that this item is nearly 35 years old, and I cannot guarantee all functions will work. Also, please be aware that there is no warranty. Furthermore, I have displayed the output on a computer monitor using an RCA-to-HDMI converter during the functionality check. I purchased and maintained this for storage, but I am selling it due to decluttering. The Super System Card and software used for the functionality check are not included. I will pack it carefully for shipping. 【Product Notes】 Super System Card and software are not included. The interface unit cover has many scratches. The controller has scratches. Retrobrite (yellowing removal) has been applied, but yellowing may reoccur. 【Included Items】 ・PC Engine Main Unit ・CD-ROM2 Drive ・Interface Unit (including cover) ・Controller ・AC Adapter 【Functionality Check Items - Confirmed with I/F Unit Connected】 ・HuCard, Audio Output ・CD-ROM2, Audio Output ・Super CD-ROM2, Audio Output ・Music CD, Audio Output ・Controller FR terminal output has not been confirmed. 【Maintenance Performed】 [PC Engine Main Unit] ・Exterior disassembly and cleaning, Retrobrite application ・Internal disassembly and cleaning ・Contact restorer application ・Exterior waxing [CD-ROM2] ・Exterior disassembly and cleaning, Retrobrite application ・Internal disassembly and cleaning ・Pickup gear replaced with a new one ・Moving parts greased ・Contact restorer application ・Exterior waxing [Interface Unit] ・Exterior disassembly and cleaning ・Internal cleaning ・Contact restorer application ・Exterior waxing [Controller] ・Exterior disassembly and cleaning, Retrobrite application ・Internal cleaning ・Button contact cleaning ・Contact restorer application ・Exterior waxing [AC Adapter] ・Exterior disassembly and cleaning ・Internal cleaning ・Exterior waxing #PCENGINE #CDROM2 #INTERFACEUNIT #RETROGAME #NEC #PI-TG001 #CDR-30 #IFU-30A
