Yes, you can steal some space from swap, but use care.  You'll have to wipe
out both the sash and the swap partitions and tell the A/UX kernel that its
playground has shrunk.

My apologies if the following sounds a little too simplistic...

a) Back up your sash partition.  It's only 3 floppies worth.
b) Boot from a disk with HD SC Setup ("Utilities 1" or whatever).
c) Make sure the proper drive is selected and click the partition button.
d) Click the "Custom" button.
e) Select and remove both the swap and MacOS partitions.
f) Create new partitions of the desired sizes.  Do not make the swap partition
   smaller than your physical RAM, 5MB in your case.  (I've used 7MB
   comfortably on systems that weren't doing lots of compiles.)
g) Click "Done" and "Quit."  You should now have your new "sash partition"
   visible on the desktop.
h) Restore everything you backed up earier and start A/UX.
i) Use kconfig to update the kernel.  Type "kconfig -n /unix [return]".
   At the blank line type "SWAPCNT=size [return]" where size equals the
   number of KB you allocated to the swap partition times 2. (For 7MB this
   would be 14336.)  Type ctrl-d.
j) Shutdown (if needed) and reboot (or powerdown) and you're done.
