Commodore FujiNet Quickstart Guide
Version and Date: June 2023 The information in this page is relevant for the time around June 2023.
FujiNet for Commodore is still under development and hardware is still in the experimental stage. FujiNet uses the IEC bus so building a prototype for testing is fairly simple, needing only 6 wires and an ESP32.
You need an ESP32-WROVER Devkit board (minimum 8MB Flash, 8MB PSRAM), a DIN 6 plug and some wire to connect them. We recommend using the official ESP32-DEVKITC-VE made by Espressif. We have also had success with the Lolin D32 Pro which also has an onboard MicroSD card socket. Pinouts are defined in software and it is easiest to match the pinout of our generic IEC board.
If you have a FujiApple Rev0 (FujiNet for Apple II) you can use it to test Commodore by building an adapter cable using the pinout below:
When configuring the firmware build, use build_board = fujiapple-iec.
You can follow the Board Bring Up Guide to install PlatformIO and build firmware for Commodore.
Since there is currently (summer 2023) no working CONFIG for C64 FujiNet you have two options to configure the FN for your local network.
- Pop the SD card and copy a working fconfig.ini file with Wifi section
- Set the info in BASIC
This will cover option 2 above.
First, go to upper/lower mode ( press the commodore key and shift)
then enter this, substituting in your SID and PW:
OPEN1,15,15,"SETSSID:SSID,PASS":CLOSE1
Reboot the FN and it should connect to your wifi.
- startup C64 with Fujinet attached to IEC
LOAD"ML:NETCAT",8
RUN
In the NETCAT Type:

Try out the Slideshows in PETSCI!
There are two network disk devices running in the CBM firmware: the standard (for FujiNet) TNFS device (given number 12 for CMB kernel) and the ML (Meatloaf) HTTP device
Loading via TNFS should be familar if you have used FN on other supported platforms.
Note about CASE: In these and other examples you may see the LOAD command used with URIs that are upper or lower case. Due to the strangeness of PETSCII you should always be typing in UPPER CASE. When the URIs are sent out to the remote servers they will become lower case. So even if you see an example in lowercase here, type it on the Commodore in uppercase.

LOAD"TNFS://FUJINET.DILLER.ORG/C64/CDS-TEST.PRG",12
RUN
Loading via meatloaf is done with the ML: prefix in the LOAD command. Some samples are below. All the programs are
LOAD"ML:GAME$",8
LOAD"ML:EMPIRE",8,1
LOAD"ML:DIGDUG",8,1
