Raspberry Pi Software - Raspi OS, Pi Imager,
2023-03-02: back home, I realized my error and wrote the 32-bit version of Raspi OS (lite) to the card. I used a different usb to wired network dongle, and could see activity lights both on the Pi Zero and the usb network dongle, but I could not connect to the Pi Zero. Oh well.
2023-03-02: still at Bitraf, I wrote latest Raspi OS (lite) to a 16 GB microSD card usin the Pi Imager. Unfortunately, I wrote the 64-bit version, and couldn't figure out why the machine wouldn't boot (it didn't have a monitor connected). I got a usb hub from a friend, and borrowed a usb network card so the Pi Zero was attached to a wired network.
