#FujiNet is a network adapter that attaches to the SIO (Peripheral) port of an Atari 8-bit computer system to a WiFi network; however, it has become an all-encompassing SIO peripheral emulator. The current hardware is a design based on the ESP32-WROVER module and contains a custom 3D printed SIO Plug and Receptacle, allowing users to attach real SIO devices simultaneously with #FujiNet.

    I ordered a FujiNet device from VintageComputerCenter and received it in short order. I plugged it into my 800XL, for which I have no external peripherals, powered it up, and it immediately displayed a list of local SSIDs. I typed in my password, hit return, and in no time at all it connected me to my home network. I connected to one of the online source servers in the list and loaded up one of the programs to test and all seems well. I’m looking forward to seeing what else this gadget can do! Thank you!

    I have been using a older Fujinet that I built myself for many months now, but wanted to upgrade to the newer Fujinet 1.0 boards. Not wanting to solder all those tiny surface mount parts, I jumped on ordering a complete built unit(minus case) from Vintage Computer Center within minutes of him putting them up for sale. The PCB looks great with great workmanship. Plugged it into my 800XL and it worked great. Upgraded to the newest firmware using the flash tool on Fujinet.Online(new updates come out very often). A BIG Thanx to everyone involved in the Fujinet Project. If you use a Atari 8-bit, you need a Fujinet. ATR/ATX/XEX loading, WIFI Modem/BBS, Print to PDF over WIFI, Load files from TNFS servers located all over the World, and so many other great features.
