The “new” Microdrives , designed especially for the ZX Spectrum , are set to change the face of personal computing by providing mass on-line storage.
Each Microdrive can hold up to 100K bytes using a single interchangeable storage medium.
The transfer rate is 16K bytes per second , with an average access time of 3.5 seconds.
And you’ll be able to connect up to 8 Microdrives to your Spectrum via the ZX Expansion Module.
