What is FujiNet?
FujiNet is a multi-peripheral emulator and WiFi network device for vintage computers. The first completed hardware was for Atari 8-Bit computers and development has begun for other systems with the goal of supporting as many as possible. What sets FujiNet apart from other WiFi devices is the new Network Device (the N device, or NDEV). The N device allows vintage computers that do not have enough processing power to handle TCP/IP connections talk to the modern internet over WiFi. Virtual adapters have been created for many protocols including: TCP, UDP, HTTP, FTP, TNFS, HTTPS (SSL/TLS), SSH, TELNET, WebDAV and JSON parser.
In addition to its extensive networking capabilities, FujiNet also emulates a wide range of classic peripherals, including:
- Disk Drives with support for local disk images and network-mounted volumes
- Cassette data recorder/player interfaces
- Modem for BBS communication over the internet
- Printers with output to PDF for saving or printing with modern printers
- Network Clock providing real-time clock functionality over the network
- SAM Text-to-Speech (Software Automatic Mouth) for authentic Atari-style voice synthesis
These device emulations let your vintage system load software, save data, print output, and even speak text—all through a single, compact WiFi-enabled module. Not all platforms support every peripheral that FujiNet can emulate which is dependent on how FujiNet connects to the vintage computer. At minimum, every platform supports Disk Drives and the Network Device.

The FujiNet project is 100% completely open source, software and hardware. All code and hardware designs are available on our Github. Anyone is welcome to join us and add support for any system they want. We are more than willing to help where we can. The best way to get in touch with us is on our Discord server.
