   werden.


   Die Hauptplatine der ATW800

   IMST800D-G20S = INMOS T800 Transputerchip (U2)
   SCX6B150WMD   = BLOSSOM Farbblitter (Entwicklungsname Charity
 Der Unterschied zwischen BLOSSOM und CHARITY
 
 The graphics processor has been completely re-designed.
 Bus arbitration scheme supports local and non-local 
 memory. Specifically useful for VME cards.
 Memory interface is improved. Blossom performs full bus 
 cycles when she is bus master.
 Events: Two sources - video scan line and termination of 
         blit.                                              
 Refresh: Blossom resets to 'Refresh enabled'.

) (U66)
