NEC CD-ROM2 interface unit for PC Engine. - Brand: NEC - Model Name: CD-ROM2 - Compatibility: PC Engine Thank you for viewing. The condition is difficult to see in the images, but there is discoloration (yellowing) due to aging. Also, the base of the AC adapter has been repaired, and while I confirmed that it powers on, it sometimes works and sometimes doesn't... Please consider it as a junk item. Please examine the images carefully and purchase, as this is a long-term storage item (everything in the images is included).
