SD interface

Exist any easy schematic for connect SD card to ZX ?
No CPLD, no FPGA, only classic schematic.

I find only:

It's possible to connect SD to AY or Centronix :) and emulate SPI interface (it's very easy, but very slow). No CPLD, no FPGA, only wires:)))))

Speccy-2007 - is the best choice!

Orionsoft made software SPI on AY chip - http://zx.pk.ru/showthread.php?t=4221 .

P.S. On MSX was an attempt to make SPI ports AY, source code attached. (Ports AY on MSX is used to connect joysticks).
