Virtual ECM Tesh Bench
I have always thought it would be cool to simulate an ECM on my home computer. To have a test bench in my PC. Of course, I have no idea how to make that happen. 
.......found something interesting the other day.

I've been using THRSimm for a while now.
Here was a thread on the subject https://www.thirdgen.org/techbb2/sho...ight=simulator
I like the package but haven't figured out how to simulate the communication to the external devices. It is capable (I think)
All of the I/O are standard 68HC11 formats that are called by the Motorola names PA1, IC1, Port C, etc
It allows triggering events etc, for IRQ's like from the DRP input.
Can't get it to fully function as an engine without waiting for an interrupt. Kinda gets so far and then just refreshes the ram.
The DRP triggers an interrupt to jump to the next loop.
Its probably my ignorance of the deeper function of the processor and the code because the program lets you define/add stuff pretty much everywhere. I can run sections easily, just can't get the whole bin to keep going. (Not applying battery power to the right pin type of thing) Code runs and can watch execution and see why things happen.
Can set sine or square wave inputs, watch with scopes, watch any memory address...
Pretty neat and for $50, can't say it hasn't been worth it.
