Vintage Dell PS2 QuietKey Keyboard SK-1000REW #2.  Minimal to no yellowing of any keys or frame, tested but there may be some keys that need their contacts cleaned.  This is a simple procedure requiring only a  screwdriver, cotton swabs, and alcohol.

These are a good compromise between the highly coveted mechanical "clicky" keyboards and modern ones that have the ergonomic feel of a typing on a slab. ;-)

Minor damage to cable jacket, covered and of no consequence except appearance.

Note: This a PS2 keyboard.  There are adapters for PS2 to AT keyboard, as well as to USB so it can be used on an older or newer PC.

Thanks for looking,
