On 9 May 2021, I tagged release 0.1.0 of OqtaDrive, simply titled “first alpha release”. It was a hobby project that had sat on the shelf for a while, until discussions over at World of Spectrum revived it: an Arduino Nano pretending to be a bank of eight Sinclair Microdrives, for the ZX Spectrum with Interface 1 as well as the QL. Five years and 34 releases later, time for a look back.
