SmartPort vs. Disk II

SmartPort (IIc, IIgs, and IIe with Saturn or third-party card) allows FujiNet to present up to 4 virtual drives. Disk II (II, II+, older IIe) presents a single drive. Check your hardware to choose the right FujiNet variant.

Step 1: Connect the hardware

  1. Power off your Apple II.
  2. For slot-based machines (II, II+, IIe):
  3. Insert the FujiNet card (or a Disk II card with FujiNet attached) into Slot 5 or 6.
  4. For IIc / IIc+:
  5. Plug FujiNet into the external SmartPort connector on the back of the machine.
  6. For IIgs:
  7. Connect to the SmartPort connector or install in Slot 5.
  8. Insert your microSD card if you have one.

Power off before connecting

Always power off before inserting or removing cards and peripherals on Apple II hardware.

Step 2: First power-on and Wi-Fi setup

  1. Power on your Apple II.
  2. Watch the FujiNet activity LED:
  3. Flashing — booting / connecting to Wi-Fi
  4. Solid on — connected and ready
  5. Slow pulse — no Wi-Fi configured
  6. If this is a first-time setup, FujiNet broadcasts a FujiNet-XXXXXX access point.

Configuring Wi-Fi via the setup hotspot

  1. Connect a phone, tablet, or laptop to FujiNet-XXXXXX.
  2. Open http://192.168.4.1 in a browser.
  3. Enter your home Wi-Fi SSID and password, then click Save.
  4. FujiNet reboots and connects to your network.

Step 3: Boot CONFIG

On Apple II, CONFIG is accessed as a bootable disk image that FujiNet presents automatically:

  1. Boot your Apple II normally — FujiNet presents the CONFIG disk as the first drive.
  2. The CONFIG program loads and displays the main menu.

See Using CONFIG — Apple II for a complete walkthrough.

Step 4: Mount a disk image

  1. In CONFIG, go to Hosts & Devices.
  2. Select an online TNFS server or your SD card.
  3. Browse to a .PO, .DO, .DSK, or .2MG disk image and select it.
  4. Assign it to a drive slot (S6D1, S6D2, etc.).
  5. Exit CONFIG and reboot — the image will load.

Troubleshooting

Symptom Likely cause Fix
Apple II shows ] BASIC prompt, no CONFIG Card not recognized in slot Try a different slot; ensure card is fully seated
CONFIG loads but can't connect Wi-Fi not configured Reconfigure via the FujiNet-XXXXXX hotspot
Drive not found (I/O ERROR) Wrong interface type Ensure you have the SmartPort vs. Disk II correct variant
