Good working condition with a few cosmetic scratches. All knobs and inputs working. Original TASCAM power supply included plus an USB-B to USB-A cable to connect to your computer. I was using it with Windows 10 with no problems - recognized by Ableton and Reaper DAWs. Driver is available here (can't include a link but you can search it easily enough): tascam.jp/int/product/us-1800/support

Does NOT include original packaging or Cubase, sorry. (Banana not included either.)

And now some descriptive copy from the TASCAM user manual:
