Never heered of it meself. There ARE PC programs out there for auto diagnosis, but the only ones
I've seen are OBDII based....there may be some that wil werk on the older, non-OBDII systems.
You can prolly buy a Snappy scammer off ebay for almost nothing these days, and have full diag capabilities, and two-way commands, in some cases, as well as troubleshooting tips/info.
Just a thought.

As an example....
Here's one. It doesn't have the Troubleshooting cartridge for Engine, but I have a couple extras...
