I would like to find an iso for pc 386 but all I have found is for rpi arm64
We do not have a “PC” appliance. But, it’s simple enough to install Debian + ASL3. See Debian 12 Install for more info.
Also, to be clear, if you’re literally meaning “386” here is in a 32-bit-only system that is not supported by AllStarLink v3.
