Field Change Order: 2024
Date of Issue     : 
Applicable to     : Master 128


Reason for Issue:
The metal plate of the new membrane keyboard is too thick to allow the
fitting of the spire clip used to connect the metalwork of the keyboard and
PSU together. The assembly change detailed below must be implemented when a
membrane keyboard is fitted. It may also be used for the current
(mechanical) keyboards. 

Types Affected: 
All product prior to introduction of membrane keyboard 0143,700
   
Description of Change:
The spire clip, which previously fitted over the tags on both the keyboard
and PSU metalwork, should now only be fitted to the PSU tag and the keyboard
tab then placed on top. The securing screw is then passed through both the
tags and tightened into the spire clip. Note: It is recommended that a
washer (M3 internal-tooth, Acorn Part Number 0882,972) is fitted directly
under the head of the securing screw.
