SidecarTridge Multi-device: An Apps Platform in a Cartridge

+
+ +

My Mega ST 4 "Low" machine uses a SidecarTridge Multi-device, a small board with a Raspberry Pi Pico W inside that plugs into the cartridge port and turns the Atari into an apps platform. It brings Wi-Fi and a microSD slot to the machine and runs a growing catalog of modular apps, no soldering and no internal mods required.

+ +

What it does

+

The SidecarTridge Multi-device works in any Atari ST, STE, Mega, TT or Falcon. A Raspberry Pi Pico W inside brings Wi-Fi and a microSD slot, and the board interacts with the cartridge bus in real time to emulate a range of devices:

+ + +

An apps platform, not just an emulator

+

Firmware V2 reworks the device into an apps platform. Instead of one fixed mode, it runs a catalog of modular apps you can switch between in seconds, with over-the-air updates and per-app configuration. The hardware and firmware are open source on GitHub, so the community keeps adding new apps and the Atari keeps gaining capabilities.

+ +

How it works

+

Setup takes about ten minutes. Slide the Multi-device into the cartridge port, power on, and on first boot it exposes its own SIDECART Wi-Fi network. You join it from a phone or laptop, pick your home Wi-Fi, and from then on the device joins your network automatically. Once connected it shows a QR code with its IP, which opens a web UI listing every installed app, and you pick what your ST should become. On the "Low" machine I use it for the ROM and floppy side of things, alongside the Cloudy/Storm ST combo and the Gotek for disk-image swapping.
