Hello,
How can I get a SPI interface to a parallel port?
What do I need?
Can someone help me.
Or should I Serial approach?
Please reply!
Regards Frits

Read this page first so you have a good idea what SPI really is:
http://en.wikipedia.org/wiki/Serial_Peripheral_Interface_Bus

Overall it's not hard, you only need a clockable shift register with a enable and a parallel load.
Probably you can use the 74HC594 or the 74HC595 device to get it working.

Hi Frits,

I'm developping a 10 euro MSX harddisk interface right now, which is basically SPI over the MSX parallel port (with level shifting). The MSX doesn't support hardware SPI, so all you need is some assembly skills and a bunch of wires.

Regards,

Jos
