There are three popular compatibility lists:
Wacom maintains their own PARTIAL list of pen and tablet compatibility. You can find it here: Wacom Accessory Compatibility Matrix
MacHollywood maintains another the MacHollywood compatibility list.
Tablet expert Kuuube, maintains this list Kuuube's Wacom pen compatibility mastersheet. Note that in this list is tested with Open Tablet Driver, not the Wacom drivers.
As always, no matter where you see compatibility lists, ALWAYS contact product support to verify compatibility before purchasing a pen.
Below are the common compatibility pairs. These are based on Kuuube's pen compatibility mastersheet and Wacom's published information.
Notes:
This list only includes those combinations that have full compatibility. This
list also excludes some very old Wacom tablets.
Always verify compatibility with Wacom support before you purchase any pen.
