On the 64, the decoded IO at the user port makes this a trivial task,
and I'm not sure if the AppleII has a serial card or not.
Take a look at my
second reply. SPI to 8-bit parallel using a CPLD.
But for the Apple code, no software in the bridge itself.

I apologize, I must not be communicating effectively.
1) User in another country
2) Owns an SPI peripheral he wants to talk to
3) Has wire
4) has Apple II of some vintage
5) can attach wire to various A2 ports, if needed.
Given those items, and only those items, is there anything that can be done?
Adding a uC or a CPLD at this stage adds testing time, development time,
and it's not what we'll need for the eventual solution, so I'd rather
avoid it if possible.
