I consider the K3S to be what Gordon Bell called a “mid-life kicker”. That is a 
technology upgrade with small changes to the design. It extends the life of a 
product without the cost of a major redesign. It can be a very smart move.

For example, the VAX-11/785 was the same as the VAX-11/780, but built with a 
faster logic family so it was 50% faster. That is a pure example—a DEC 
spokesman called it “bug for bug compatible”. 

This is the section on “mid-life kickers” from a long chapter by Bell, Mudge, 
and McNamara about technology and product strategy.

And of course, you stay on top by obsoleting your own stuff before your 
competitors do that.
