Pinbot shipped with System 11a or System 11A CPU boards. Both these boards support only 6116.
You must have the NVRAM configured to support 6116. The image on Pinball Life is small but it looks like the jumper is configured for 6264. The board itself looks to support 6116 but you will have to remove the 6264 jumper and install the 6116 jumper.
The actual CPU board in your machine may differ. A lot of boards were swapped between machines so the board in your machine will dictate whether or not it is directly support.
Unfortunately there are a few variables here that interact with each other. You will need to see what you have and what you get to figure out direct compatibility or if some modifications are required.
Contact Pinball Life or Rob Anthony if you want to be sure. The above is an assessment based on public information and images. I have no direct experience with this product.
