John Woods has written a version of mapalloc() and mapfree() (in machdep.c) which allow multiple simultaneous mappings of the Unibus map. I have integrated it into my version of 2.8 and 2.81. The only problem I have is that it is still possible for the system to hang up trying to swap if it can't find enough contiguous registers (strategic registers being used by hung-up DMA devices). I can make my version available. John Stewart, Teledyne Geotech, (703)276-7900
