Up for sale is my OTC Monitor2000 scanner. I used to use it on the '83 H/O since that was all original. Asking $100+shipping. Anyone with an original G-body that still has the ECM can use this for troubleshooting (or any other GM from those years). I found it invaluable when troubleshooting sensors and other issues.

Here's a pic of it and the manual.
