FujiNet for Coleco ADAM


The ADAM FujiNet is a multi function peripheral for the Coleco ADAM Family Computer. It currently provides floppy disk emulation, DDP (cassette) emulation, printer emulation and an all new network device. This single device has everything you need to use the Colecovision ADAM in the 21st century.

This device requires a RJ12 6PC6 Crossover / Reverse phone cable to connect to your Coleco Adam. This cable is added to your order by default, but can be removed if you already have one or want to make your own.

FujiNet for Coleco ADAM comes with an assembled and tested circuit board in a 3D printed case.*

FujiNet has a built-in CONFIGuration disk that loads when you start up the ADAM. In CONFIG, you can setup your WiFi network and select which disk images to mount in the virtual drives. Disks can be loaded from the on board MicroSD card socket, or from TNFS servers over the internet or your own personal server.

Multiplayer cross-platform games for retro computers is now possible with FujiNet. ADAMcala is a mancala game written for Coleco ADAM and has support for network game play (video). There is also a port of Connect 4 for both the ADAM and ATARI that provides cross platform play (video).

The hardware is a carrier board for the Espressif ESP32-DEVKITC-VE development module with 8MB of PSRAM and 8MB of internal flash storage. On the carrier board are supporting circuitry for connecting to the ADAMNet bus, IN and OUT RJ12 ADAMNet ports, 3 push buttons, 3 status LEDs, an ON/OFF power switch and a push/push MicroSD socket. All this fits in a custom designed 3D printed enclosure.

Your ADAM Fujinet will come with the most recent Firmware and updates can be installed with the FujiNet-Flasher on Mac, Windows and Linux.

Note: ​The 3D printed parts used in FujiNet are not like injection molded parts. I strive to produce good quality prints but some may show extrusion rings, artifacts, blemishes and other signs of plastic extrusion.

*The product image shows a typical setup. Monitor, Coleco ADAM, cartridge, cassette, and joystick not included. FujiNet for Coleco Adam comes with one ADAMNet bus cable, but can be de-selected before checkout if you already have one or want to make your own.
