Thanks for the insights! The ASM function is coming next but not likely to be today unfortunately.

Side note, all the functions are under my control of course so I can make them behave as required.

Alright found a few minutes after work here, don't have a whole lot of time during the week. I'm going to keep a running log of the investigation here until I collect it all. Maybe I can write it all up when done.

Compiling the following code with WDC816CC

I'm learning the ropes by building it on a breadboard ...
