I've got a few Pacman pcbs I'm having fun with. Some have heat sinks on 4 of the memory chips. Most do not. Where can I get these heat sinks and what do you use to glue them down properly?
I personally use small copper RAM heatsinks like these: http://www.ebay.com/itm/281033685901 . They come with thermal tape, so you just peel and stick.
I'm not really sure. I bought the official manual and it is listed on the schemetics as having heat sinks. But I've seen a lot of pictures of boards without. But with the cheap price of them I'll error on the side of caution.
Somewhere I've got a big bag of the black anodized heatsinks for 14/16-pin DIPs. Way more than I'll ever use. IIRC, the fins on them run the other (short) direction. If anyone needs a few, figure $0.50 each and $3 shipping.
