I am planning on buying a new hard drive and either the RAMFast or apple's 
new SCSI card.  What I was wondering is do I have to have a DMA memory card
in order to use either of the new SCSI cards?  I realize that it won;t be as
fast without DMA, but will they still function properly with the plain ole
apple expansion card?  

My second question is wheter or not most of the available DMA cards that use
SIMMS, use the same SIMMS found in most macintosh models?  I have access to
about eight 256K SIMMS, and it would be nice to get a card that use them(
They came from a Mac SE and a Mac II).

Lastly I was wondering if anyone could tell me the format of $C1 type pictures.
Like for insstance where is the palette infomation, and where is this information supposed to be placed if you where to bypass the toolbox and put the picture
driectly into screen memory. And speaking of screen memory, is the shadowing 
of banks 00 and 01 always on, or is it neccesary to activate it somehow?
