Got Wozmon up and running! 🍎 - with an assist from the beneater subreddit, where they found an issue with the schematic on the Max232 chip! Exciting. Going to experiment here for a bit then onto Basic!

Got ROM and VIA hooked up to the 6502! Wrote a simple program that toggles the VIA portB between AA and 55 hex (lights are the binary representation). Relieved was able to get here, troubleshooting the random error I was seeing was truly daunting heh. Grateful to y'all for the suggestions!

🎉 The 6502 project is underway! 🎉
* Arduino to better understand what the chip is doing (output in serial monitor is address / data / read-write bit in binary & hex)
* Running off the clock I built earlier
* Next up: Hookup up the ROM

Clock Module done! Going to use this to power the 6502 project. Hopefully will have more to share next weekend.

Clock Pt 2 down; monostable mode. Same chip as astable, but acting as a debouncing circuit here:
