Pretty fun. Definitely could use some practice lol. Also first few tries I really struggled not to press tab. Fun stuff ty for sharing!

Did a Parks on the Air (POTA) activation in PVD yesterday with my brother on 20 meters. I think 31 stations activated. Got a few in Canada, fun stuff. Fun hammin' 📻📡

Technician's License in the bag. Was graded by the delightful radio group WM7X. Will get my callsign sometime next week, hopefully before my first HT arrives. 📡📻

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!

ACIA mostly hooked up. Still need to do the control lines so I can actually address the new chip, but gonna have to wait til next time.

Gonna start the #6502 UART module for a proper RS232 interface (so I can hook up Wozmon / Basic) this weekend.
Until then I'm starting to read some brain candy my brother recommended...the scholomance series for Naomi Novik (just a fun relaxing read hopefully):

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!

First program on my 6502 that does meaningful work.
Writes something to the A register then stores it at a specified location ( 6000 in this case)

Got the ROM installed. Can now actually program the Microprocessor! More to follow.

🎉 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.
