So what does all this mean?  I am not thinking really hard about getting a
DMA hard disk because as I understand it, if I want to load a program into
fast memory I am not going to be able to do it using DMA anyway!  Is this
not true?  Maybe it could be DMA'ed into the chip_memory, and then be
moved by the CPU to fast_memory, without having to worry about the interrupts.
Is this true?  

More important than this is, if DMA _is_ important even if you _don't_
care about loading data in for real-time stuff (like loading sounds while
the sound chip is playing the old data, or loading animation objects), than
is the C-LTD board DMA?  Not at that price I would think not.  But the PAL jr.
is not available with a developer discount.  The MicroBotics _can't_ be
DMA, and that leaves who? ASDG? Do they have a DMA hard disk coming out?
Does anyone else?  I just can't afford $1500 and was about to plunk down
the $995 (or so, love that Amiga credit card) and get the C-LTD SCSI
board and drive.  Isn't this going to be a fine disk for programming with?

It still passes the bus don't it?
