Baby Pac-Man vidiot board upgrade????

Got my Baby Pac-Man back and it works great, or shall I say worked
great. It lasted 2 full days then it died.

Upon further investigation, I found out that the MS9928 chip got very
hot and that was probably the reason for it dying.

My question is; how do you install a heat sink on this chip? Is there
something documented somewhere?

I also got to get a couple fans inside of there, it gets very hot
inside that cabinet (worse than Q*bert, and I thought that cabinet was
the hottest one that I have).

After about 3 hours, I reseated a bunch of chips on the vidiot board
and got my 10 blinks and the game plays again. I even turned it off
and on a few times to check it and it worked every time.

I got it turned off right now and don't really plan on having it on
until I get this problem taken care of, at least as far as I can take
it.

Any help would be awesome.

Thanks.

Digi-Key (and others) sell 40 pin-DIP heat sinks. These clip lengthwise
over the chip and cost about a dollar. I include one when I sell a NOS
TMS9928A...
