On an unsynchronized manual transmission, you either have to double clutch (which will be required on any road test or "float" the gears. For the actual shifting patterns, diagrams should be readily available online.
I've never heard of an Eaton Fuller 12 speed, nor am I able to find any references to one via Google. I've driven Eaton Fuller 8LL, 9 speed, 10 speed, 13 speed, and 18 speed transmissions - could you be thinking of one of these? IIRC, Volvo marketed a proprietary 12 speed transmission, and Meritor offered a 12 speed automatic, but not Eaton Fuller.
Yes, there's a transmission filter.
I want to see the shift patterns
It shifts itself.
No, 10 speed does not convert over. You would need to get a truck with either a 13 speed, or a 9C transmission (which is convertible).
The words "Super 10" refer to the Eaton 10 speed heavy duty manual transmission.
The Eaton-Fuller and Rockwell websites should have them. Google images will be able to find images, as well.. you just put in "8LL shift diagram", "9 speed shift diagram", "10 speed shift diagram", etc.
It's a 10 speed unsynchronised transmission which only incorporates five major shift motions. It works in a similar fashion to the top side of a 15 speed, except you must shift progressively through all the gears.

No. Unless you have a "C" transmissions (e.g., RTOC, RTLOC, etc.), it's not convertible. A 10C transmission doesn't convert to a 13 speed - a 9C transmission does. A 10C converts to a 15 speed, which remains essentially a 10 speed with five deep reduction gears.
Every one I've had a chance to take a look at has had a 10 speed.. I'm pretty sure they were Eaton Fuller.
