     For the sake of some kind of standardization, may I suggest Motorola
S record Hexfiles?  At least if you use this format you will have some
chance of making use of routines generated on other 68000 systems.  The
spec can be obtained from Motorola, but here's the overall scheme:

STLLAHALDD................DDCC
^^ ^ ^ ^ ^                 ^ ^
|| | |+| |------+----------| |------Checksum
|| |  |         |                   CC= sum(LL+AH+AL+DD....+DD)
|| |  |         |-------------------LL-3 DataBytes
|| |  |-----------------------------Start Address
|| |--------------------------------Count of bytes following
||----------------------------------Type 0=Header, 1=Data, 9=Trailer
|-----------------------------------Header

                   (based on art of David L. Kindred)
