+
+Version: 0.05 Wed 22-Jun-94        Aideen McConville             
+
+Moved to new source tree.
+
+---------------------------------------------------------------------------
+
+Version: 0.06 Thu 05-May-94        Steve Cormie                  
+
+* Fixed bugs in claim/release of sound DMA channels.
+
+---------------------------------------------------------------------------
+
+Version: 0.07 Wed 12-Oct-94        Aideen McConville             
+
+* Added hdr.DMA - lists SWI names (needed for swis.h)
+  Updated Makefile to export the above.
+
+---------------------------------------------------------------------------
+
+Version: 0.08 Mon 31-Oct-94        Steve Cormie                  
+
+* Added directed comments to Messages file for message tokenisation.
+
+---------------------------------------------------------------------------
+
+Version: 0.09 Mon 21-Nov-94        Steve Cormie                  
+
+* Prevent initialisation if hardware does not support IO DMA.
+
+---------------------------------------------------------------------------
+
+Version: 0.10 Tue 28-Feb-95        Steve Cormie                  
+
+* Fixed interrupt disable imbalance in DMAGetRequestBlock.
+
+---------------------------------------------------------------------------
+
+Version: 0.11 Fri 03-Mar-95        Steve Cormie                  
+
+* Fixed SWI DMA_TerminateTransfer when called with no supplied error. DMA
+  manager was looking up its own but failing to clear V before calling
+  DMATerminate and so left a terminated transfer blocking the queue.
+
+* Now keeps interrupts disabled at the end of the final interrupt for a
+  transfer when the transfer is removed from the queue etc.
+
+* Added NOPs to macros which could change processor mode.
