#189847 - Von Neumann first
Responding to: Maarten Brock's previous message
Hello,

Yes, the XCODE/XDATA access can be made compatible with a Von Neumann scheme by making a few changes in the state machine. This is where I will start.

As for the OCD interface, I wanted it to be useable without any external hardware, so that you don't need e.g. an RS-232 to C2 interface in order to play with the core. I don't know yet how difficult this is going to be.

So for the time being I will just add some form of ISP-over-RS232 and leave the debugging interface for a later stage.
