Difference between a Cat 623E scraper and a 623super E

[Dirt Shifter]

Hi there, can anyone tell me the difference please between a Cat 623E scraper and a 623 super E?
Is it a year thing or is it an option thing. I am looking at a 623 E, 1993 model, not sure which one it is, is there anyway of telling the difference please?

It is a year thing, super was built from
93 to 98, has 35 more horsepower, a piston
Pump supplying the elevator and a bent
Axis piston motor for the elevator.

Check the prefix 6CB = 623 E, 6YF = 623 Super E
