Working on the debugger (arduBug). Basically a little tool that I’ll use to manipulate the W65C02 processor and any devices on the bus. Its working well firmware-wise so I’m working on the host to let me interact with the nano65 (the actual computer) on a more abstract level. If all goes well I’ll hook up the VIA soon and from there on all sorts of cool things will be possible. In the picture you can see the full setup (arduBug, motherboard, and storage board). The oscilloscope shows the internal clock (2.5 MHz; will likely be decreased to 2 MHz). The interesting thing is that the arduBug boots up and turns off the internal clock to overwrite it with it’s own clock source. I was now able to revert that setup from the host software via a serial command.
