ALDL +ECM document

[DAVE_HEMPSTEAD at HP-Andover-om3.om.hp.com]

Hi,
   A month or so ago, someone posted a document on a GM ECM from either the late
80's (88-89) or early 90's describing how that software worked, and a bunch of 
the ALDL commands.  It gave a very nice description of some of the filtering 
done on the signals, and how some of the engine settings were calculated.  
Unfortunately, I didn't keep an electronic copy, and have been asked for a copy 
of it.  Can anyone re-point me to this document???

THanks,
Dave Hempstead
