I have a box of 1227808s that go to limp-home mode after 
running fine for various periods of time, if only they 
each had an identifiably bad part!

Which raises a question:

By inspecting various disassemblies, I've noticed that 
(some) BINs have the ability to download code into RAM 
and execute that code via ALDL commands. I assume that 
there is therefore a (PC or otherwise) based program 
that loads various diagnostic routines into the ECM and
can (maybe) determine what's broken.

Anyone know anything about this?
