Neat!  So, has anyone tried porting the BSD ramdisk driver to A/UX?
That's one way to sort of get more free space elsewhere, since you could put 
/tmp and multiple swap areas on multiple boards. (maybe 1 swap/board, since
you might be able to fool the swap strategy routines into conserving nubus
bandwith like they would disk interface bandwidth in deciding which disk to
talk to.) At least A/UX isn't crippled like SunOS in terms of addressable 
memory (I hear from 3rd party memory vendors that you can physically address 
64M in a Sun-3/160, but only 24M is supported by the OS.  Quite a shame.)
