Vintage Adesso 305 Extended ADB Keyboard for Apple Mac Green Alps SKCL

Missing 1 key cap (see photos). This has green switches which are Alps SKCL's according to another seller. I hooked this up to an old Powerbook and tested it, they keys all work but I had to press some of them multiple times to get them to do anything, it is therefore listed as 'for parts or not working'. This has 2 ADB ports which work as well. Thanks for looking!
