Why???  Why NO OBJECT SWAPPING in Smalltalk/V 286???  I bought it for 
my 1 Meg machine, only to discover that I couldn't run the bit editor
or clone my system because 1 Meg was not enough!  

Actually I assumed Smalltalk/V did NOT object-swap since V 286 did not.
Because of that lack I decided to do a product (I write games) in C
instead; overlays are painful but I can run in 512K.

Now I have to go re-think my choices...  

Digitalk, are you listening???  Object-swapping gives Smalltalk/V 286
the equivalent of Virtual Memory!  Applications of *any* size can run
on a lowly PC (or even AT!).  This is a big deal; you should install
it *right away* on the 286 version.
