FujiNet

FujiNet is a multi-peripheral emulator and WiFi network device for vintage computers. The first completed hardware was for the Atari 8-bit line of computers and development has begun for other systems (Coleco ADAM, Apple II, Commodore 64, Atari Lynx, ZX Spectrum and more) with the goal of supporting as many old systems as possible.

FujiNet was created to be a network adapter but has become an all encompassing peripheral emulator. Devices currently supported include disk drives (with support for booting disks stored on remote servers), printers (output downloaded from the device as PDF), modem (BBS access over telnet) and the all new network device (N:).

The N device allows vintage computers that do not have enough processing power to handle TCP/IP connections themselves to 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 hardware is designed around the ESP32-WROVER module with an available 8MB PSRAM and 16MB of built in flash storage. A custom 3D printed SIO Plug connects directly to the Atari and the Receptacle allows for daisy chaining other peripherals on the SIO bus. The MicroSD socket can be used for storing disk images.

The firmware is open source licensed GPL3 and the hardware is certified open source hardware by OSHWA, licensed CERN OHL 2.0.

FujiNet welcome anyone to build their own device but for those unable to do so hardware is currently being built in small batches.
