ET-3400 Memory Map boundaries aren't provided

[ricknun]

The Memory and Disassembly panels show ROM and RAM (hardware boundaries) but not all boundaries given on page 87 of the ET-3400 manual: Monitor ROM, Not Usable, Displays, Not Usable, Keyboard, Not Useable, Optional 256 bytes User RAM, 59 bytes monitor RAM, 197 bytes user RAM. A thought: Make the Memory and Disassembly fields address only (remove ROM, RAM and the entire choice selection) and instead load a default Memory Map file that includes all the ET-3400 boundaries mentioned. (I would order them from low numbered address to high, instead of as shown on page 87.) The Disassembly panel then clearly shows how close user program/data is getting to important device boundaries. Consider adding another tab, resulting in Breakpoints, Device Map, and User Map. The Device Map would be the ET-3400 (or ETA-3400?) boundaries. The User Map would be the auto-loaded same-name map functionality done already.

Added after submission: Warnings or red highlighting could be given if user program/data ever appeared in the wrong place, like the Not Usable or ROM areas.
