Sinclair ZX-interface 2

Sinclair made some interfaces to enhance the posibilites of the most successful product, the Sinclair Spectrum , those interfaces include the interface 1 (allow to connect to microdrive units and serial RS-232 interface ) , the ZX-printer interface (thermal printer and this interface, named "interface 2".

This interface allow to connect two joystick to the spectrum , using the "Sinclair type joystick", that usually links the numeric keys to the joystick and the other facility provided by this interface was the use of memory cards with games and utilities that allow to start running applications and programs without loading them from tape.

Unfortunately the cartridges were quite expensive so few games were produced in this format, also it was ROM (read only memory) so people can't save their own games in them.
