NEC Home Electronics, Ltd. PC Engine Interface Unit CD-ROM Player The above 3-piece set The operation check is as follows: ・PC Engine Main Unit Operation confirmed. RF output is also OK. The image of Kato-chan Ken-chan is a picture taken with a camera of the screen output via RF. ・Interface Unit Operation confirmed within the last month, but currently, I have gotten rid of the AC adapter, so no recent confirmation. ・CD-ROM Player Since there is no AC adapter for the interface, the operation of the PC Engine CD-ROM2 software has not been confirmed. I confirmed the operation of the CD-ROM software on the PC-8801MC, which is compatible with the player. Also, I played a music CD on the player alone and confirmed that it was playing normally from the line output. Sound is coming from the earphone jack, but there is a scratchy noise when touching the volume. The condition of the middle gear has not been checked here. No price reduction
