Hi there,
I'm sorry if this is the wrong place to post but I'm hoping someone can help me identify the hardware seen below (fitting into an unrelated green casing) - image taken circa late 1980.
I would also be grateful if someone could enlighten me as to the meaning of the secondary set of characters above the normal QWERTY characters. I've seen them elsewhere but don't understand their significance.
Many thanks if you can help!
