SidecarTridge

SidecarTridge is a Spanish hardware studio founded in 2023 by Diego Parrilla. The company designs and manufactures modern accessories, replacement parts, and development tools for vintage computers—primarily the Atari ST, STe, Mega ST, and Mega STE lines, with growing support for Amiga platforms.

SidecarTridge products include the Multi-device Emulator (a cartridge that emulates ROMs, floppy drives, hard drives, and RTC functions), the TOS and ROM emulators, ST2VGA video adapters, USB-C PD power supplies, and the ACSI2STM solid-state hard drive family. Every product ships with detailed documentation, field-upgradable firmware, and as little soldering as possible, aiming to make vintage machines easier to maintain.

The company operates from Madrid, Spain, and ships worldwide via its online store and partner marketplaces. Technical resources, firmware, and reference designs are published on the documentation portal (docs.sidecartridge.com) and the official GitHub organization. SidecarTridge maintains an active community through its Discord server, blog, and YouTube channel.
