OK, well as someone else already pointed out the Stamp does not run at 133MHz, but even if it did it wouldn't matter. You've fallen into the "megahertz myth" trap here. What that means is that you can't compare two different processors (Pentium versus BASIC Stamp) even if they run at the same speed. The reason for this is that each different type of processor does a completely different amount of work with each tick of the clock. Also remember that the BASIC Stamp (as well as all the other microcontrollers inside the OI/RC) is only an 8 bit processor.

This is exactly why it makes no sense when people compare a 2GHz Pentium to a 1GHz Macintosh and claim that the Mac is slower. It's apples and oranges.

Also the change from PBASIC 2.0 to 2.5 has nothing to do with the processor. You should be able to use new 2.5 code with an old robot controller, because the tokenizer converts it all down to the same machine instructions anyway.

BTW, it's been a while since I looked at it, but I believe the other 2 processors in the RC are PIC16c74s.
