I had just started working on something very similar with the data and address LEDs, but this is much nicer than what I came up with. I was tinkering with the idea of doing some kind of indicator with the phase 2 clock signal to help with troubleshooting also

Glad you enjoyed it. I recommend you stick with it though, for these kinds of projects the experience of building is worth it in itself :-)
