New BSP from Tony R. Ambardar <tonya@ece.ubc.ca> from the

University of British Columbia.  The BSP is for:

    Yes, this is the "entry model" of a series of boards from Technologic
    Systems. Costs <$200 I believe. They have a WWW page at www.t-systems.com.
    I am letting them know about the availability of this BSP too.
