The following is from Digitalk's "Scoop" newsletter, spring 1989
issue:

	"Since the last newsletter, Smalltalk/V has been joined by
	Smalltalk/V 286 and Smalltalk/V Mac.  Here is a comparison of
	features in the three:

	* The original Smalltalk/V runs in 512K bytes (up to 640K),
	  has 16-bit pointers, uses an object table, has a 64K byte
	  maximum object size and does object-swapping to disk when no
	  more memory is available.  Smalltalk/V 286 and Smalltalk/V
	  Mac run comfortably in 1.5 Mbyte of memory, have 32-bit
	  object pointers with no object table, support objects larger
	  than 64K and will use as much memory as you have with no
	  object swapping.

	* Color is available for Smalltalk/V as an extension kit;
	  Smalltalk/V 286 has integrated color graphics; color for the
	  Mac is not available yet.

	* Multiporcessing is available for Smalltalk/V in Goodies #1;
	  Smalltalk/V 286 and Smalltalk/V Mac have it included in the
	  product.

	* Smalltalk/V's source-level debugger has been extended for
	  Smalltalk/V Mac and Smalltalk/V 286 to push-button debugging
	  with the ability to set breakpoints and single-step through
	  code.

	* Smalltalk/V has a 10-chapter tutorial; Smalltalk/V 286 and
	  Smalltalk/V Mac have two extra chapters on application
	  design and development.

	* All have complete environments with graphics, overlapping
	  windows, menus and mouse support.  Smalltalk/V Mac's
	  environment is the standard Macintosh environment.

	* All come with the same example file on disk including the
	  bit and form editors and object-oriented Prolog."

I have no affiliation with Digitalk other than as an owner of
Smalltalk/V Mac.
