5 Years of OqtaDrive

OqtaDrive, an open-source hobby project that emulates a bank of eight Sinclair Microdrives for the ZX Spectrum and QL using an Arduino Nano, marked its fifth anniversary on 9 May 2026, five years after its first alpha release (0.1.0) on 9 May 2021. The system streams data over a 1Mb/s serial link to a Go daemon on a PC or Raspberry Pi Zero, which handles the heavy lifting, and has grown through 34 releases to include direct loading of snapshot and TAP files, ZXDB software search, a cartridge file system, and CP/M support. Hardware designs by contributor Tom Dalby, who also open-sourced Z80onMDR, range from a micro version to a standalone unit with an onboard Pi, and the project was publicly shown at the Vintage Computing Festival Berlin in October 2021. A key milestone came with release 0.7.0 in April 2024, which turned OqtaDrive into an Internet gateway for the 1980s Sinclair Network using minimal added hardware (one transistor, four resistors), enabling remote file transfers, chat, and network gaming without modifications to vintage machines. The project has since moved to Codeberg, added private on-demand networks and stability fixes in 0.8.4 following stress testing by Hans Kramp. Watch for continued hub service development and community adoption among retro-computing enthusiasts.
