For those interested in a Prime "Benchmark"...

[StephenG1CMZ]

I have now uploaded my implementation of a translation of the original Algol benchmark into PPL to the software library, although I still haven't found test results for that benchmark on-line.

This should be seen as a "Yes the Prime can run the benchmark", rather than a real measure of what speed the Prime is capable of achieving.
I am sure there are plenty of optimisations that could be done.
