Help in identifying bad memory chips/finding replacements on Omega Race

Hi,

I have an Omega Race that doesn't work (bought non-working). I've done the requisite battery removal, and as far as I can tell, there's little/no damage due to leakage. I can get the board to power up in test mode, and though there's no sound and no picture, the LED player start buttons light up and have told me I have a total of 10 bad chips (7 of one type, a pair of a different one and a single one).

The numbers on the chips are a bit cryptic, though after looking at all of them, they seem to be identified by a 4-digit number.

Can these simply be located and bought by this number?

Additionally, 2 of the 10 are ROMs (the rest are RAM). I'm guessing the RAM ones, if replacements can be found, won't be an issue, but the ROM ones will need to be programmed somehow, is this about right?

Are my only options to buy other boards and hope to get lucky with good chips, or can these actually be bought new? And how can I buy the ROMs programmed?

Thanks very much,
Ryan
 
The ram chips are all 2114's. I got a tube of them for cheap off ebay when I was repairing my Omega Race. You can get the roms burnt from hobbyroms.com. I wish you luck repairing this board. I've been fiddling with mine for about 2 months now and it still isn't working. The graphics section is outputting garbage vectors. You can tell the program is running because when you pull one of the ram chips it will give you the ram error flashes, but for some reason it has some random watch dogging.
