I'm confused about some beasties referred to as Static Column RAM.  I have 
several questions, the answers of which will probably lead to more questions.
1) What are the differences between SCRAM and DRAM? 
2) What, if any, additional functionality does one gain by using SCRAM?
3) Which does my A3000 have?  (5 meg ram.  1 chip, 4 fast)
4) The reason I'm asking is because of a mode called Burst mode for the 68030.
   When I type CPU from the shell, I get the following information:

    1.DH1:files cpu                                                     
    System: 68030 68882 FastROM (INST: Cache Burst) (DATA: Cache NoBurst)

   What does this mean, exactly?  (I am familiar with some other machine 
   architectures, I just don't know much about the 68030.  Please explain 
   this in highly specific detail.  Thanks)
