Editing Psion Series 3mx Hinge Repair (section)

== Donor lids ==

The 3mx uses the same '''480 × 160''' panel as the [[Psion Series 3a|3a]] and [[Psion Series 3c|3c]], so those lids fit physically.<ref name="spec">[https://www.psion.netogram.com/psionspecifications.html "Psion specifications"], netogram.com. Source for the shared 480 × 160 screen across the 3a, 3c and 3mx, and the Series 3's different 240 × 80 panel.</ref>

Three cautions:

* '''A [[Psion Series 3|Series 3]] lid will not work.''' That machine has a 240 × 80 panel and a different ribbon.<ref name="spec" />
* '''Every 3mx is backlit''', where most 3a and 3c lids are not.<ref name="wp3">[https://en.wikipedia.org/wiki/Psion_Series_3 "Psion Series 3"], Wikipedia. Source for the universal backlight on the 3mx, its late and largely US availability on the 3c, and the matte silver finish.</ref> Fitting a non-backlit donor lid will lose you the backlight.
* The 3mx is '''matte silver'''; the 3c is dark grey and the 3a is a different shade again.<ref name="wp3" /> A donor lid will work, but it will not match.
