Vintage Apple Extended Keyboard II Macintosh Mac ADB M3501

These keyboards came from the shuttered Houston Computer Museum. They were tested by the previous musuem caretaker, but I have not personally tested these. I don't have any more ADB cables to bundle with these keyboards at this time. Also, I did not put the sharpie checkmarks (the last caretaker of the museum was sadly not a fellow collector).
Multiple units are available at the start of the auction, with a sampling of available keyboards in the photos above.  Product shown in photo shows the shape for this model of keyboard, and is not the precise unit being shipped. Multiple units are available to purchase, each bid of quantity 1 receives 1 keyboard. Rubber feet may fall off or disappear over time because the glue is not strong enough. Products are previously used and pulled from a working environment. Keys are firm to the touch, and as a result, keys may not respond immediately or register quickly when pressed. See pictures for a representation of what the keyboard model shape looks like. 
Since these keyboards are over 25 years old, they are being sold strictly AS-IS with no returns accepted.  These do NOT include cables.
