I have two old (ancient?) Pi's Model A, which I use in air quality displays. Due to the issues with WiFi dongle I needed to flash new SD card with current version of Raspbian Lite. The problem is that version from 2018-11-13 does not boot on my Model A boards (ACT LED does not blink), while it does boot on Pi 1 Model B. I checked two different power supplies and tried system in vanilla state and after upgrade to most recent state.
Any help or suggestions much appreciated.
