is anyone modifiying an emulator to recreate the phosphoric delay and crosstalk synchronization - possibly the latter was not suffered by enterprise folks but it sure as heck would genuineify they zx spectrum emulators
also the emulator that can run rzx files can replay a full program including the keypresses - is this possible on enterprise
try fuse and zx spin
or real spectrum if you want to emulate the DMA in the MB-02+ disk interface
