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.

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.

Atari 8-Bit

The #FujiNet project began as a simple WiFi modem for the Atari 8-Bit line of computers and quickly grew into a super peripheral emulating many devices including disk drives, printers, data cassette recorder, modem and the all new network device.

Atari FujiNet hardware is produced in small batches and when available, are in the shop or from other vendors across the globe. You can also build your own using the design files.

Apple II “FujiApple”

The FujiApple Rev1 hardware is now available. It uses the Apple II Smartport bus which works on the IIc (ROM0 or later, not ROM255) and newer machines with no additional hardware. FujiNet can be used on a II/II+/IIe with a SmartPort card (softSP, Grappler+ with softSP, A2Pico woth softSP). It will also work on the Apple III with SmartPort card and custom cable. Disk II is supported as read only, SmartPort drives read/write. See the quick start guide on the wiki for more information.

Coleco ADAM

The ADAM and it’s ADAMNet serial bus was the second system completed and officially supported by FujiNet.

ADAM FujiNet hardware is produced in small batches and when available, are in the shop or from other vendors. You can also build your own using the design files.

Commodore 64

C64 support is in progress and targets the IEC bus. Much of the development support provided from the Meatloaf project.

Tandy Color Computer

FujiNet for the Tandy Color Computer (1/2/3) prototype hardware is available for building. The current design is in the form of a cartridge with a pigtail to connect to the serial port. Communication is handled via the Drivewire protocol. Experiments are being done to use the cartridge interface with a RP2040 (Raspberry Pi Pico) as a bus interface for the ESP32 FujiNet.
