Buildable NodeMCU Wi-Fi modem for the Commodore 64 user port with voltage level shifting and status indicators.

The complete project remains downloadable. Retro-Updates listed an assembled revision-2 version for the C64 and C128, but it was out of stock on 2026-07-30. Revision 1 fits only the smaller WeMos NodeMCU v3 form factor; revision 2 supports both common board widths.

Adds Hayes-style Wi-Fi modem access and ZiModem networking functions to a Commodore 64 through the user port.

The maker page exposed current eBay and Amiga on the Lake purchase routes on 2026-07-30. The buyer's-guide card and cased listings are one hardware family; confirm the enclosure, board revision, and installed firmware with the seller before ordering.

Period cartridge interfaces connect a C64 or VIC-20 to PET-style parallel disk drives, printers, modems, and other IEEE-488 equipment.

These are original period interfaces to find used or reconstruct from archives, not current products. Match the cartridge to the exact computer and verify its ROM. The original C64 software occupies part of the $C000 area and disables serial IEC; Andre Fachat's separate modified C64 KERNAL can retain both buses, but it is not part of the cartridge.

The seller's collection listed the modem as sold out on 2026-07-30. An optional case is an accessory for the same modem family. The product page does not provide a public firmware or complete hardware build package.

Adds high-speed Wi-Fi networking, file-transfer protocols, and SD-card storage to computers with a standard RS-232 interface.

The maker page exposed direct eBay, Sphere Cube, and Arcade Shopper purchase routes on 2026-07-30. Tavily could not independently extract the exact eBay or Sphere Cube destinations, recorded as WF-044 and WF-045, so confirm current stock before ordering. A user-supplied 5 V micro-USB supply is required; the SD card, serial cable, and computer-specific adapters are not included.

Current ZiModem-based Wi-Fi modem for Commodore 64 and 128 BBS access, Hayes commands, and incoming connections.

User-port Wi-Fi modem for connecting a Commodore 64 or 128 to Internet BBS services.

Retro Electronics listed two assembled modems in stock on 2026-07-25. The ESP8266 is flashed and configured, but terminal software and the separate device needed to load it are not supplied.

Adds Wi-Fi BBS and Hayes-modem access through the user port of supported Commodore computers.

The standard display-free version and both PET versions were out of stock on 2026-07-30. The standard OLED page still said a new design was pending and did not offer ordering. Check the direct pages for a restock or revised design.

Connects supported vintage computers to Wi-Fi BBSes through an RS-232 serial port.

The current Pro V2 model was in stock on 2026-07-30. It has a female DB25 connector, a color TFT screen, a printed case, faster interface buffers, and signal-state LEDs. It needs an external 5 V micro-USB supply, and the host may also need a gender changer, DB9 adapter, or correctly wired computer-specific serial cable. The older display-free and OLED WiModem232 models are discontinued and replaced by this version.
