A friend has unearthed approximately (5) of these IBM keyboards in his dad's shed in MN. These are not PC keyboards but instead likely 3178 terminal keyboards. They probably came out of 3M a very long time ago. https://drive.google.com/file/d/1B8kw9xdaeikwzKzyL0ts3HZZg96K7Yov/view?usp=… I have persuaded my friend not to trash them until I see if there is interest in them here. They are dirty and their working status is completely unknown. Contact Gary: w0ghz(-at-)comcast.net if you are interested in them.
