Seek contract work: DSP chip asembler (56001, TMS320); C, C++
John Strawn
I am looking for contract work programming on DSP chips. I have
extensive experience on the Motorola DSP56001 family and the TI TMS320
family. I can easily learn other chips (Analog Devices, AT&T,
Sharp...). I can also do C and C++ work on Macs, PCs, and UNIX.
Recruiters are welcome to contact me for contract work, but I am not
interested in a full-time employment (w-2) position.

Seth Wardersman
I will definitely post a resume if their is an interest but it seems
that this is not the place for jobs that I am looking for. I am a college
student at Duke doing C programming. Hopefully I would I like to get a summer
internship doing some more C. Is there anyone at all that accepts interns.
Thanks,
