It took me a moment - the LGP-30 is a computer that uses magnetic drum memory and is not a musical instrument from the 1980's.

I'm curious if the ferrous oxide is still attached to the drum. I would suspect the heads need cleaning - being clogged with magnetic particles that have flaked off the drum.
