        Due to Engineering Changes in the 7000, additional jumpers were    
     added (W98,99,100,200,201) increasing the board's flexibility.  These 
     are marked with a (+).  Newer models also added an LED and fuse for   
     term. power.                                                          
        Software for the 7000 comes from Columbia Data Products, called    
     SST.  The OEM version of the board is the 7000-ASC, and the consumer  
     version, with the SST software, is called 7000-FASST, or 7000-FASST2. 
        The Hardware design was sold to Future Domain Corp. in 1991.
