Following on from the interrupts work, I now have the RTC, a 100hz timer and millisecond 32 bit-counter up and running. The 100hz interrupt can be switched on or off, the millisecond timer starts counting at system start. That I think is the last of the hardware for the moment. Time to move on to creating a small boot routine to load up a larger program from the sd card. I've been using my own version of the zBug monitor which I nabbed from this project when I first started on my own 68000 system. I wouldn't have got started without that project and the Easy68k simulator.
