The Acorn Progressive Establishment Testing System (PET) was the middle stage in the test equipment supplied by Acorn (between the FIT  and the ICE) for the BBC Micro. It was capable of running an extensive range of tests on the BBC Micro which allowed a good test engineer to locate the most awkward of faults in a relatively short time.

I don't know where the various cables connect to the BBC Micro.

I do not have any documentation or software for the Acorn PET.
