3.0
	the first version I know.  One executable, TURBO.COM, 39k,
	included library--editor--compiler.  Pretty awesome, eh?
	Silly 64k constraint on data and code. No seperate
	compilation.  Terrible overlaying.

4.0
	Units.  No 64k constraint.  Better overlaying.

(the climax as far as I'm concerned)
---------------------------------------------------------------------------

5.0
	Integrated Development Environment
	debugger available from within environment

5.5
	OOP

6.0
	trash

7.0
	pond slime (windows)


Honestly, why did they go off into flaky stuff???!
How about writing a better compiler i.t.o. generating better
code?  Why not a -O where he compiles slower and emits better
code?  Why not better hooks for mixing (say) TP and TC?  Etc.!
