  2. A few i/o lines to a bin to decimal decoder chip which is then connected to
    the eprom/flash chip enable lines. Then write some code to calculate
    branches, if branching to an address space in a different rom, toggle i/o
    lines accordingly. Easy. BTW, you may want to add a few wait states when
    switching, depending on the speed of the rom.
