I have a DK cocktail in the shop with a board-related graphics issue. It is a TKG-3 4-board set.

I brought another DK 4-board set from home for testing purposes, but it is a TKG-2. (and it is missing a couple chips on the SOU board.)

The TKG-3 has 4 ROMs on the CLK pcb (4M, 4N, 4R, 4S) and 2 ROMs on the Video PCB (5H, 5K).

The TKG-2 has 6 ROMs on the Video PCB (3A, 3B, 3C, 3D, 3G, 3H).

Since it's probably a bad idea to hook up TKG-2 Video and CLK pcb's to TKG-3 CPU and SOU pcb's (with corresponding ROMs), is it possible to swap the 6 ROMs on the TKG-3 to the TKG-2 and make it work? And which ROMs match each other for the swap?

Any help would be appreciated...
 
Almost, but that appears to be for the 4-board TKG-3 only.

I need to know if the same ROMs will work on a TKG-2, and if so, where do they go...
