This appears to be an IBM Personal Computer XT Model F 83-key keyboard. It's a clicky, mechanical, buckling-springs style keyboard with a 5-pin DIN connector.

Please note that the label on the back is faded away so we cannot confirm what model it is.

It is in decent condition, all keys spring properly, but as we are unable to test it, it is sold "As-Is," for parts or repair.

There is a small chip in the plastic on the underside, and the whole device has mild wear from use,

we wiped it down but it could use a deep cleaning to get it looking newer. See photos for details and bid accordingly.
