The first two bytes in a FAX.TIFF file are 2 ASCI characters "II"
(0x4949) ... (little-endian), and "MM" (0x4D4D) ... (big-endian) within
a 16- or 32-bit integer. The 42 is a two byte integer value so either
0x2A00 (little-endian) or 0x002A (big-endian).

This stuck with me because in the original description the statement was
made that files (viewed as ASCII which is an OS assumption) started with MM
or II (I got that stood for Motorola vs Intel) followed by ("arbitrary but
carefully chosen character *") When I did a.i.'*' and observed that it
was 42, I assumed it was homage to Douglas Adams and have smiled about it
ever since.
Since there are two byte to represent 42, I think they are talking about:
a.i.(,:|.)'42'
52 50
50 52
Here, 52 50 would be bigendian order (most significant to least
significant - what another message has suggested is the 'wrong' order)
and 50 52 would be littleendian order (least significant to most
significant). Presumably there was some mnemonic reasoning going on
here, when that spec was getting written?
Also,
a.i.'*'
42
is only one byte.
(Or am I missing something?)
