Hey Ed,

IMHO they are pretty ineffective as they don't make good thermal contact
with the chips and usually trap more heat than they sink. If you've got an
old PC graphics card, they often have heat sinks on the RAM chips which make
decent MOS heatsinks.

BTW - which model/revision is it? I don't think I ever saw an original
breadbox with a metal FCC shield on anything but the VIC-II. All mine just
had the cardboard one (long since removed). I only ever saw metal sheilds on
the 64C and 64G.

My motherboard has a factory shield/heat sync on it.

Since you seem to have gotten an original MOS-PLA, you might consider
putting a heatsink on it.
