- changed interrupt usage for Int2 instead of Int6 
    (after discussion with Matze about "best" approach)
  - see HW_INTSOURCE in hw.c for the active interrupt source
  - this build reflects changed word handling in CPLD code,
    now all addresses below $6000 are presented as Big Endian
    words, such that copies of the frames can be done with
    fast instructions like movem

(IMPORTANT: not _yet_ true for current CPLD build)
Matze's card does selective byte swapping for different areas of the chip within
the CPLD. This step enables Big Endian reads/writes to the hardware registers. Since
the SRAM would be byte-swapped as well, the latest (WIP) version of the CPLD presents
