Mini Byte: ZX Spectrum Smartcard v3

While surfing the 'net I came across a video on this card, so thought I'd splash out and see what it was like and I have to say I'm impressed. It combines a boot rom selection system with an SD card loading system, a Kempston joystick interface and a Diagnostic card, all in one neat package!
