I just built a half assed version of the simple two transistor cable and hooked it up to my 88 TPI. I connected the aldl with a 10k resistor. I started WinALDL and turned the car and and let it idle a bit. For some reason It wouldn't give me all the data, just this:
Time RAW:MW2 RAW:PROMIDA RAW:PROMIDB RAW:IAC RAW:CT
0.2 0 0 9 0 122
0.6 32 18 12 0 122
0.9 32 0 14 100 133
1.2 0 0 17 0 122
1.6 32 18 19 0 122
All the other fields are left blank, and the data I got looked kinda eratic. All the flags where unchecked. While in neutral I tried revving the car a bit, and it actually stalled out after a while, which is the first time my car has ever done that.

 

Nevermind, I fixed this by simply rebuilding the cable a bit more carefully.
