Question

Hey,
I have an original 2board donkey kong pcb set that has started displaying some graphically issues. see attached images..
it started just last night while playing the game with only a few little dots at the bottom which i noticed right away and over the next 10 minutes or so turned into a line. i decided to turn it off as it was late. after some research today i tried checking voltages and it all seemed fine. i removed my dk remix board and put the z80 cpu back into the socket on the main board to rule out that as an issue (unfortunately snapping a pin on the remix board in the process. anyway thats a separate issue that i will be contacting the manufacturer about for possible repair)
Anyway. i turned the machine on and it all seemed fine for about 10 minutes and then the dots and eventual lines started appearing again.
After some more research online i stumbled across this website.
http://www.brasington.org/arcade/tech/dk/
and noticed that the lines were starting to match one of the images on the page.
It looks like a Bad 3P (2716) chip. as you can see from the website. the colours even match exactly to the error generated through mame.
So, just wondering if anyone has or knows where to buy these and if they would kindly beable to program/flash the chip for me so that i can attempt to replace it and see if that solves the issue.
(i have noticed that mikes arcade sells sets but as i only need one would prefer not to have to buy a full set as they arent cheap for the lot of them.)
I would greatly appreciate any help.
thanks,
this is the location on the chip on the video board. and supposedly that chip is "3P = v_3pt.bin" from the mame romset.
