I-O DATA DVD-RAM DVR-AM16CV Unused LF-M821

Thank you for looking.
This is an I-O DATA ATAPI internal DVD-RAM cartridge compatible DVD Super Multi Drive (White) DVR-AM16CV.
The drive itself is a Panasonic LF-M821.
This is a rare item nowadays that can use cartridge-type DVD-RAM.

This was purchased as a spare for work.
I am listing it because I no longer use DVD-RAM.

The warranty stamp area on the box has been cut out, and the box is damaged, but the drive itself and accessories are unused and unopened.
I checked the accessories, and it seems that the 4 mounting screws for the PC are missing. I don't think this will be a particular problem.
Other software and manuals appear to be included and unopened.

I considered testing the drive before listing it, but I couldn't set up an ATAPI connection environment at home, so I gave up.
Therefore, as this is a very old item, I cannot guarantee its operation.
I would appreciate it if those who need it would purchase it with the understanding of this point.

Thank you.
