What do you hope to do with it?

What machine do you want to use it in?

Just trying to identify a few components to sell ideally, raising last minute Christmas cash. I get a fair bit of vintage electronics come in but have had to put a lot of things on the back burner since we had twins

It's a circuit board from a 5.25" hard drive -- MFM, RLL, or ESDI.
