Probably already got, if you've got that far.

Figure 11, page 14 has some diagrams explaining.

EDIT EDIT: Weird, need +5V on A0 of the 68882... would never have guessed that.
Thats what i used for reference and thats how I wired it.

VCC to A0 and SIZ. 32 Bit bus wired and DSACK0/DSACK1 wired to the 030. Not much to go wrong here from what i can tell.

If i get nowhere i'll drop the FPU into memory space and poke at it from there. (One of the amazing things about the CPLD setup i have)
