I recently picked up a SUPERBIKE (DK conversion) daughter card and rom kit, and when it comes to the three roms AS, AN, AY (i believe off the top of my head) I am unsure where to put them. Does anyone have the inst manual or a pic of their board that I can use as a reference? (I found pics of three board on the web/ebay, each are different from the dc I have)

(I also have 8 Ball and Hunchback, so I am kinda familiar with these kits)
 
here are pics, the dc with the roms, and a close up of the dc. The dc is labeled DK1, the cpu is labeled MAB2650A, GRG8307M0Y

I don't have but I would believe that As is 5b and Ay=5c and Ap=5d on the CPU board. As long as you put in socket with the chip in the right direction it wont hurt the chip. I'm guessing here cause normally they are listed in mame in order of chip on board. Also the daughtercard plugs into the Z80 socket

I was thinking they would go on the DC, but if you look at the pic of the DC I have, there are no other sockets for the roms on there. I've seen a few different DCs, so that must be the issue why my set is not working.

Anyone have a pic of their DC they can email/post?????
 
I saw that too a bunch of unpopulated area. Most conversion boards have a few proms a couple 74ls series chip and a 40 pin cpu ic not a z80 but like a 2650A chip.
