Schematic for 730 ECM?
Anyone know if there exists a schematic for the 730 ECM? I'm poking around in AUJP code and a lot of these things would make a lot more sense if I could glance at what is connected to what. I'm talking about a schematic of the actual board itself, not the wiring diagram from the ECM to the sensors and such.

Re: Schematic for 730 ECM?
Ah very helpful thanks! While I'm asking, it looks like some registers are in non-standard places around 0x4000. Is there a datasheet for the chips used for these ECMs or are they proprietary versions of the 68HC11's to a certain extent?

Re: Schematic for 730 ECM?
Figured as much. Are there mapped out regions where either registers or memory-mapped peripherals are? Essentially anything which is not OK to move to a different variable or memory location? I'm sure I can figure it out eventually by reading the ASM comments but if someone has the whole range off hand that would be nice.
