Ok, I've moved these photos to the wiki... hope everyone is ok with this.
It can be found here:wiki/index.php/Atari_ST_motherboard_revisions
The order might need to change and the text (regarding add-ons etc.) should probably be added too...
EDIT: I think the order should be based on the Cxxxxx number, not the revision... doh! :/
Please take note of the filenames used, it would be nice to keep these: ST_Motherboard_Cxxxxxx-xxx_Rev_x_x.jpg
