alpha_ninjaHi there! Long time no see!
Here's what I just found out.
All cartridges share one bus.
This makes sense.
So, I tested inserting one cartridge after the other.
Magenta is doing the sensing, I'm inserting black, then cyan, then pigment black, then yellow.
Magenta only

I don't know why I didn't test for this.
Anyway, these are the conclusions I can make from this:
1. The read protocol is as follows:
0xdef800 (Yellow) 0x*****
0xdefc00 (Pigment Black) 0x*****
0xdee400 (Cyan) 0x*****
0xdef200 (Magenta) 0x*****
0xdeec00 (Black) 0x*****
2. The write protocol is as follows:
0xdf2c64 (Black)
0xdf2432 (Cyan)
0xdf3c32 (PgBk)
0xdf3832 (Yellow)
0xdf3232 (Magenta)
Edit:
Turns out the cartridge I used for testing had the traces cut. Oops :P
I've added the values I got from another test, but won't be retesting the values I measured above :)

Well, what I'm afraid of is that these things have vastly smaller storage space than I initially assumed. That would suck.
Also, not that related, but https://github.com/NicholasCLewis/InkShield is cool.
