FujiNet was intended to be a network adapter that attaches to the SIO (Peripheral) port of an Atari 8-bit computer system but has become an all encompassing SIO peripheral emulator. Designed to physically interface with any 8-bit Atari system via the SIO port with a 3d printed SIO plug. Also has an SIO jack on the back so that other peripherals can be plugged in as passthrough devices. Powered from the Atari (unless it's used on a 400 or 800, they don't supply enough current).
Emulates data storage on cassettes and floppy disks. Data can be stored on SD card or TNFS network share. Emulates the 850 modem. Emulates most of the common Atari printers, but converts files to PDF and saves them. Implements a brand-new network (N:) device.
Implements Bluetooth, NTP, text-to-speech.
