OqtaDrive began as a hobby project to emulate a bank of eight Sinclair Microdrives for the ZX Spectrum with Interface 1 and the QL. Its Arduino Nano acts as a protocol converter, streaming cartridge data over a serial link to a Go program on a computer or Raspberry Pi, where most of the work happens. Early development focused on reliable basics: detecting Spectrum and QL systems, working alongside real Microdrives, and providing installation tools and a web interface. Support for loading snapshots and TAP files, browser-based upgrades, control from the vintage computers themselves, software searches through ZXDB, cartridge editing, and CP/M followed over the next few years.
A major expansion arrived in 2024, when OqtaDrive connected the Sinclair Network - an early-1980s local network used by the Interface 1 and QL - to the internet. With a small hardware addition and a connection to a hub, users can exchange files between vintage machines across the world without modifying the computers or installing extra software. Later additions include private, on-demand networks, simpler addressing for network games, and hub-based chat and echo services. The project’s five-year history traces a shift from practical Microdrive emulation toward making original Sinclair networking usable over modern distances, while continuing to improve stability under heavy load.
