A few weeks ago I found out that there was no M13 wiki page so i told myself to make it since I love Model Ms.
I search on reddit for M13 and found 5 different P/N. I'm sure there is loads of them but can't seem to find them.
I currently have the :
-1378192 (wikified but needs pictures from the owner, it's been 7 days since I asked him and he was ok, those he posted were just not really nice)
-06H4173 (wikified)
-82G3281 (I need the owner permission to use his photos)
-92G7461 (wikified, more photos maybe ?)
-13H6705 (Haven't done it yet but will likely be wikified by this evening)
You can always provide picture for the already wikified ones. Some of those are not the nicest...
btw here is the page if you want to check it out : [wiki]IBM_Trackpoint_II_Keyboard[/wiki]
