To enter Skandha Morpho, bring up the Skandha3 emulation under Skandha4 by typing
at the commandline. After a short pause to load needed lisp code, this should bring up a blank graphics port with the Skandha3 menu down the right-hand side. (Performance may be sluggish on Personal Iris (4D/20) class machines; It is fairly reasonable on Indigo2 class machines.)
Select the "System Menu" entry from the bottom menu. (Note that Skandha4 uses a one-button-mouse model, and always uses the middle mouse button on three-button mice.) This will bring up the standard Skandha3 system menu. Select "Morpho" from the bottom of the menu. There will be a short pause while Skandha4 loads the Skandha Morpho application (which is written entirely in lisp -- xsk3-morpho.lsp). You should then get the "MORPHO FILE MENU", the gateway menu to Skandha Morpho proper.
