0x08 is PORTE and the difference is that E7 is high unplugged and low plugged in.
0x0A is mmcctl0 which is strange, but i've repeated the experiment a number of times without seeing it high again.
0x13 is mmcctl1 which is also strange, but this is always 0x05 value without the cables plugged in. I'll have to investigate this! It *could* have something to do with the porta behaviour!!
0x32 is PORTK which is strange, this could be to do with the memory registers!

0x00 0x10 0x20 0x30 are all CAN3 registers.
0x00 is CTL0, flag is "in initialisation mode"
0x01 is CTL1, flags are "listen mode" and "in initialisation mode"
0x06 is TFLG, flags are each of the three transmit buffers is emtpy
0x20 is the RX region and thus full of garbage by the looks (I believe it's a RAM implementation, so this is not surprising...)
0x30 is the TX region, not sure why it is zero, perhaps a more traditional physical representation or some init logic or something.
0x40 is PORTT as is 0x41 both show that I have pull ups on the RPM inputs ;-)
0x48 is PORTS as is 0x49 both show the lower four pins as ON
0x4C is the pull up/down register, all PORTS pins are in pulled state
0x4D is the pull direction register, all but the first pin S0 are in the pull up state, S0 is in pull down
0x50 is PORTM as is 0x51 both show the lower four pins as ON
0x60 is PORTH as is 0x61 both show all 8 pins as ON which reminds me that they are inverted and pulled up externally. I'll repeat with the CPU card unplugged from the rest of the stuff and see what differences there are.
