In theory, the Spectrum can support 8 microdrives, and the QL already having 2 could support 6 more.
I just wondered if the ZX Microdrive mechanism, i.e. the drive part, was replaced by a QL Microdrive, would this solve the situation. If so, then the ZX Microdrives could be updated to QL standards...
ANother question comes to mind, can QL Micrdrives work in ZX Microdrives attached to Interface 1?
Maybe need a IF1/MDV Tech Guide.
