Just remembered this isn't the case as I bought an MDS-JE480 a few months back. No remote and a bit scruffy looking but I was only after the MDM-7S1A drive as a donor for an MDS-JB980 with a persistent C13 issue.
Had an initial set back as the 480 threw up a C13 error and then refused to eject the disc I had put in it to test it worked but after a quick belt swap it seemed to be in good working order.
A check in the service menus showed the 480 had far fewer "miles" on the clock than the 980 (21 rec/119 playback vs 108 rec/536 playback) so hopefully it'll have a fair bit of life left in it.
Swapping the drive unit over was straightforward enough (had a bit of advice/moral support from @kgallen 👍) - almost a direct swap, although the drive in the 980 had an additional earth wire so I connected that to the donor drive as well, and I am now back up to a full complement of working 980s 🙂
