The schematics can be found e.g. at http://files.shrak-mobile.com/schem/motorola/C139_schem.rar. They apply to C139 as well as C140, as they are very similar.

=== Bootloader ===

The loader is pretty much identical to the loader in the C123.  However, it has one additional nastiness:

 * After the download has completed, it expects the magic string "1003" (0x31 0x30 0x30 0x33) at the RAM address 0x803ce0

 * To bypass this limitation, use the Calypso romloader to chainload the application. Here's an example for loading [wiki:layer1.bin]:
