Default p72 chip help

Ok I have a p72 I am chipping.
Name:  p72.jpg
Views: 83
Size:  224.2 KB

Dont have anything hard soldered in yet.

Do I jump J1 (I have read about a j10 I cant find). I have a capacitor in c51 and c52 (have read you do not need these in a p72). The main problem is I can find no r54 do i use r52? I got the dip in and 74hc373 in I also have a 4 pin in cn2.

Any one running a p72 Do I have any of this rite? There is a lot of bad info out there on ---- forms just trying to weed threw it all.

No one has had crome working with freelog? Should I just go crome pro and make it easy? Has anyone tried this http://forum.pgmfi.org/viewtopic.php?f=52&t=14026 using the new protocol for freelog?
