Uh... depends on what KIND of cpu ticks you need for your job.

IF	1. You can fit it memory-resident into a Mac,
	2. It is not floating-point or even multiply/divide
	   intensive,
	3. It involves a lot of pointer arithmetic, character
	   banging, and terminal I/O (like a typical editor),
	4. You don't need fast file I/O (or your Mac already
	   has a "net disk"),

THEN a Mac is indeed almost exactly 40% of a VAX-11/780.

If the app violates #1, YOU LOSE. If it violates #2 or #4, your
figure of 1/15'th of a VAX may be high.

You have to compare apples and... Oh, never mind.
