==== Description ====
The Xerox 928-900451 is a keyboard that was used with the Xerox II line of computers and manufactured by Xerox. The PCB bears Maxi Switch Co. markings, and uses a 25-pin proprietary cable to connect to the computer. The keyboard has only been documented to have Maxi Switch Vintage Linear keyswitches, with a dummy switch used to stabilize the "return" key, and a latching keyswitch under the "lock" key. 
==== Construction ====
===Case and Internals===
The keyboard casing is a 2 piece plastic assembly held together by clips located on the bottom half. The switches are clipped into a metal plate that is secured to the top of the case by 4 screws on the distal left and right sides of the assembly. The PCB is mounted to the plate via metal standoffs secured by screws. 
=== Keycaps ===
