Well, back to your original question... overpowering the address bus ~probably~ doesn't cause things to explode. I remember reading about a gizmo called something like the python that used a bunch of paralleled chips to override the address bus so the memory of a computer running copyprotected games could be dumped. This would have been in the Apple ][ days.
Then again, who else would be driving the address pins but the microprocessor? So it really should be safe.

Hello,

I think that it is enough to put 8K resistor to the ground on that pin (without soldering).

I have used 8K resistor to enter bootstrap mode and then I have read all memory data.

Colin Bourassa emailed me. Anybody need any help delving into the Audi S4 ECU?

If anyone finds this old thread, I've moved my work to www.nefmoto.com

Why not post the cool bits here too?

Anyone into the Delco stuff?
Or any good Delco (RE) sites

Because I have an entire website full of cool bits.

Hi Archimense,

This thread has totally piqued my interest. I've been searching high and low for ways to do an audi ecu flash via obd-ii cable if possible.

But the link you provided nefmoto.com appears non-functional.

Did you misspell it? Thanks for your follow-up on a four year old topic regardless.
