<PARA>If you are going to burn a new EPROM using the binary image,
be careful to get the byte order correct. It needs to be big-endian.

<PARA>If the byte order is wrong you will see 603c instead of 3c60
etc. Use the EPROM burner software to make a byte-swap before you
burn to image to the EPROM. </PARA>
<PARA>If the GDB stub EPROM you burn does not work, try reversing
the byte-order, even if you think you have it the right way around.

byte-order upside down.</PARA>
