Appendix IV - Using the unit with the Sinclair ZX Microdrive
The CURRAH MicroSpeech unit is fully compatible with the Sinclair ZX Microdrive and Interface I. Simply follow the setting up instructions supplied with Interface I, and plug the MicroSpeech unit into the port on the back of Interface I BEFORE plugging in the power.
Again, be sure to disable the keyvoices during all data transfer operations to prevent the "enter" keyvoice being drawn out.
