Jaty68k
Fork of a Motorola 680x0 emulator written in Java that is specifically designed to easily run and debug the linux kernel of the Katy 68k PCB project.

Building
There is an Apache Ant build file included. Just run ant from the project directory.
Running
There is a simple cpu monitor console to enable testing/debugging. This can be invoked by running the following at the command prompt:
$ java -cp m68k.jar m68k.Monitor linux-pcb.bin
Once the zBug(ROM) loads simply type "j" and then "003000" to start Katy 68k
