appear in the memory map of whatever device it will be plugged into. All
offsets are relative to the start of the EPROM.
Some programmers allow you to select an offset so reading a file with
addresses like E000 can be mapped to the right physical location in the
EPROM. ie, the programmer can be told that address E000 is actually 0000
and it will do the mapping for you.
I seem to remember using an assembler with an external tool to translate
the assembler's unique output file format to standard formats, and one of
the options was to tell it where to place the hex file output; it didn't
change the code, but would change the base address in the file to make it
easier to read into programmers.
