Internally modify OBDI computer for an OBDII car?

I want to swap my 97 Z over to OBDI and was wondering what I have to do in order to just put the OBDI computer in and not have to change anything. Anyone know?
I think the only thing I'd actually have to change is the knock sensor would have to be changed out to an OBDI sensor. Is there any way I can keep the OBDII sensor?
Is there anything else I'll have to change besides figuring out what to do with the knock sensor?

I just did a PCM swap in my 97 T/A and all I had to change was the knock sensor and the PCM it was very simple. I tried it with the OBD2 knock sensor and it's not pretty although I heard you can add a resistor or something I'm not quite sure.

Yeah, I'd like to keep my OBDII knock sensor so that I could swap the OBDII computer back in if I need to take it in for some warranty work.
This way I'm not swapping knock sensors all the time.

PCMFORLESS.com has modded OBD1 computers for the OBD2 cars that you do not have to change anything but the PCM. Programmed and shipped is $290 to your door. Your old pcm can be swapped right back in too.

Yeah, I know. I was looking for someone that knew how to modify the computer so that I could just do it.
But I e-mailed Bryan @ pcmforless and he's hooking me up with a really good deal on a modified computer with a stock program so that I can just do the modifications myself.
