I used this about 30 years ago when I was a student, and have kept it at home since then. There are some minor scratches, but overall it's in good condition. I think it's still usable, so I'd like to pass it on to someone who needs it, like a student. Wiped and cleaned with alcohol disinfectant wipes. Please purchase only if you understand that this is a used item that has been stored at home.
