Support for j1850 VPW/PWM?

So far, this is the most detailed spec I could find:


(Somene already posted this, but the thread is getting long).
It says almost nothing about the entertainment system, other than the address range reserved for it.

Hi I’m looking for an ET7190 demokit to experiment j1850PWM with. Anyone know where to get one or have one they don’t want/need any more?

Thanks.

Any news about the progress on the J1850 VPW and PWM?

If anyone is interested in this project, and inclined to take a shot at it, there’s proven VPW code here to use as a reference:

The original author of that code went offline a couple years ago, but I’m pretty sure that repo has the latest version of his code.
