Really, is that true?  If you get a hard disk that is DMA it has a DMA chip in
it that is completely seperate from the Amiga DMA circuitry?  So that must be
how the PC hard disks can be said to be DMA also.  So what does that mean for
the lowly 3.5" floppies?  They don't have their own DMA circuitry so do they
DMA only to chip memory and not to fast memory?  Is it definate that when 
an advertiser says that their hard disk is DMA then they mean that they have 
one of those full memory DMA's and are not just using the Amiga DMA to Chip
memory?  How does the sidecar do it? or is the side car just going to be slow?
Is the sidecar going to have 2 meg of sockets for Amiga memory and sockets to
bring the IBM memory up to 640K and an 8087 co-processor socket and is it going
to reach the market?

You know, in psychology (my sisters graduate degree) they say that the most
boring way to make conversation is to just keep asking questions.  So I thought
I would provide this last piece of information to spice up this letter.
