Korg D-16XD 16-track digital audio recorder great condition

Description

Korg DX-16DX
16-track digital audio recorder in great condition.
I bought this used around 2008 or so and used a lot through the years. I even used it this year to record a couple of projects and it still works great. All functions work fine.
There is one small issue - when it boots up, a message comes on saying that internal battery for the date function needs to be replaced and the internal date always resets back to the factory date of Jan 1st 2003. I'm guessing replacing the internal battery would fix it, but I never bothered since it causes no other problems or issues.
The unit includes the extra optional 8-channel analog input board for 16 inputs total.
I have an extra screen for it. I also have the original full manual and quick start manual. I even have the original box although it is not in good shape.
Here are the specs on the unit if you need it. More can be found on the Korg site. Sweetwater also has a page on it as well even though it is no longer available.
