hello to all,picked up a original donkey kong pcb lately and its a 2 board type(tkg4).its a fixer up pcb,some eproms and 3 proms were missing and i have replaced the eproms with the correct code(us set1).the trouble i have now is the 3 prom locations on the pcb.these are stated on the romset as 1.c-2k.bpr 2.c-2jbpr 3.v-5e.bpr,does anyone know what the location numbers are for the pcbs?
donkey kong prom locations?

hi,
on this schematics:
http://www.arcade-museum.com/manuals-videogames/D/dk-tkg4u.pdf
MB7052 are located on 2F and 2E and are tied to the video output stage wich is in the CPU board
another MB7052 is located @2N on the video board
looking at the mame driver:
the palette prom c-2k.bpr, c-2j.bpr should be put on 2F and 2E (maybe they must be inverted)
the v-5e.bpr should be put in the 2N location...
try and see if it works..
let us know.

hello,thanks for your info i will put these proms in this evening and power on.yes the mame driver does state proms c-2k and c-2j are inverted bits which is correct,this tkg4 board has its rgb and video sync inverted and i have got the invertor board for it for it to work correctly on my monitor.
hi to all,powered on my donkey kong pcb this evening and it came on with video and sound
,demo works but there was no sprites all missing such as barrels,mario,kong etc.selected a credit and the game played blind,all background graphics were present.colour looked a bit odd so i swapped proms 2e with 2f and then it looked right.the good news is the game is running and not crashing,now its time to fault find the missing sprites.
