The Spanish TSM30 phone's sole claim to fame is that some blessed soul who
chose to be identified as HispaPhreak has leaked, back in 2004, a complete
copy, in full source form, of a version of the Purple Labs firmware suite
for the Calypso+TMS320DA250 GSM feature phone platform.  The specific version
leaked by HispaPhreak targets the TSM30 phone hardware, hence that it is how
it came to be identified - but the IFCTF FreeCalypso project is seeking to
port it to other GSM phones based on the Calypso chipset.

HispaPhreak's original release was in the form of an ISO image for a CD,
intended for Windows-based users with usage instructions in Spanish.  The
original uncompressed ISO image weighs just under 500 MiB; hispa-cd.iso.xz
is the LZMA-compressed (lossless) form of that original image.

The actual source code, however, is fully contained in a single ZIP file of
47406704 bytes in the root directory of that CD; orig-source.zip is that file,
extracted for more convenient downloading.  The rest of the files on the CD
make up the Windows-based development environment needed to rebuild a
functional firmware image from the source.  We have extracted that environment
as well; it can be found in windows-env.tar.bz2 - packaged as a Unix tarball
for the benefit of freedom-loving developers who use Wine under Unix/Linux
rather than real Windows.
