I must say that I've never seen a 68000 (or 68008 for that matter) with a
heatsink, be it in Amigas, HPs, Ataris or industrial systems. The 68000
doesn't heat up like a Pentium or a 68040.
OTOH, could any one confirm whether the 68000 was only available in ceramics
at first? The only non-plastic one I've seen was in a very old system.
