Thanks! Without your intuition about the intensity In would not succeed.
Interesting: I thought that a strange behavior in the brightness control was a fault of my gear. I order the new EPROMs and see what it changes.
If you like, as soon as I have a draft for the new book with the 11302, I make available a pdf for you.

That is great news! I am happy that you were able to restore EA function and save another scope.
If you are able to update the firmware to 3.1, you will find significant improvements. Version 2.7 was a very clean release with no known bugs, as I recall. Version 3.1 is a feature upgrade.
Firmware version 3.1 includes many features that are available in the A-version such as histogram-based measurements(never done in an analog scope) and a one-touch shortcut to set up for delay time measurements with the counter-timer.
The most noticeable improvement is the intensity control. The early FW releases (2.7 and below) used a very complex algorithm to compute variables to manage physics of the CRT and the different intensity levels of text characters, xy trace, main trace and delayed trace. This is a messy task to make each appear independent when they all use the same MCP image intensifier. The extensive calculations required too much time and make the intensity control annoying to use. Version 3.1 is a big improvement.
