[Mark] is just starting off on his own 6502 computer odyssey. He was inspired by some of the other projects we’ve seen around here, like [Quinn Dunki’s] Veronica Project, but with a spin that leverages modern processors to alleviate some of the messy work. As you can see above, there’s an Atmel chip perched above the 65C02 processor. This chip not only feeds the processor data (through all those slightly diagonal yellow wires) but also provides the clock signal and operates the reset and bus enable lines.
This is more of a hello world post for [Mark]. The chip is simply running NOP commands right now. But it shows that the basic idea works, and the video after the break lets us see another time-saving aspect of the circuit. He’s using a character LCD to display memory location and data values. The plan is to get a blog going, which he’s hesitant to do as it takes valuable hacking time away from the project. We disagree. The write-up (although incredibly fun for us to read) ends up being a reference manual for him once the project starts to get really hairy.
