Well... that was just plain ugly! Here is how the data and address
lines are connected on the Warpspeed cartridge:

Chip pin --- Cartridge port
A0 --------- Y/A0
A1 --------- X/A1
A2 --------- V/A3
A3 --------- U/A4
A4 --------- S/A6
A5 --------- P/A8
A6 --------- M/A10
A7 --------- L/A11
A8 --------- N/A9
A9 --------- R/A7
A10 -------- W/A2
A11 -------- T/A5
A12 -------- J/A13
A13 -------- K/A12
A14 -------- VCC

D0 --------- 17/D4
D1 --------- 18/D3
D2 --------- 20/D1
D3 --------- 21/D0
D4 --------- 19/D2
D5 --------- 16/D5
D6 --------- 15/D6
D7 --------- 14/D7

Yuck! My brain is to tired right now to "fix/normalize" the raw
cartridge dump. Off to go play Planetside and shoot things.
(OT:Freekin game uses 800+MB of RAM! Damn!)
