#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. The current hardware is a design based on the ESP32-WROVER module and contains a custom 3D printed SIO Plug and Receptacle.

What does it provide?

#FujiNet provides the following functionality in various states of progress:

WorksLoad CAS files from SD or TNFS servers
WorksLoad floppy disk images from onboard MicroSD or networked TNFS server. Supports ATR, ATX, and XEX formats.
Works850 Modem emulation, supports Type 1 Poll to load handler. Works with existing communications programs such as Ice-T, BobTerm, AMODEM, PLATOTERM, and BBS servers.
WorksPrinter output saved to PDF files downloadable from the device. Available Printers: 820, 822, 825, 1020, 1025, 1027, 1029, Espon 80, Okimate 10, HTML for copy/paste, GRANTIC Screen Printer. Example 822 Printouts (PDF): Text & Graphics. Example 1027 Printout (PDF): N-Hndlr ASM Text.

More functionality will be available in the future with updates to the firmware.

What systems are supported?

FujiNet is designed to physically fit on all original Atari 8 Bit machines. Our custom CONFIG program which is loaded at power up is currently about 18k in size so it will not work on a system with less than that (stock 400, 600xl) and 24k or higher is recommended.

When will it be available?

#FujiNet development is proceeding rapidly. Since November 2019 we have created many hardware revisions and have moved software development from the Arduino IDE to PlatformIO. FujiNet Hardware development is now at v1.5 status and is being produced in small batches. Design files have been be released in our Github hardware repo.
