Tascam 244 port studio 4-track cassette recording. See all photos for details and reference. Missing some colored knobs, missing small screws on the bottom that hold bottom panel tight, it was purchased that way and can be easily replaced. Window frames are loose. Powers up when plugged in ( two right windows don’t light up as seen in picture) . All knobs turn, twist, and move up and down good. Turns on ( Untested)
