For the photo. Thierry had ordered a special edition with non-glued heatsink :-) Which came in very handy, because I had no glue pads left at the time. Practically, the Q60 almost does not need the heatsink. Power consumption is a lot smaller than of the 68040. But theoretically it needs one, so it's got one. >Interesting to see the regulator there. Why "Interesting"? >You should put stickers on the Lattice chips - easy to mislocate them >otherwise. Well I haven't been producing as many boards as you. I immediately put the Lattice chips in the socket after programming and - that's it. >Is the extra chip (U30) for Q60 underneath? Not underneath, but within :-)) The answer is the 68060 datasheet. "U30" is not an extra chip, it is just a schematic symbol to cover the extra pins in the inner rows of the CPU socket. The Q60 has a few extra wires, two different LSI chips, the regulator, an extra diode, and of course a different CPU. The other 68060 related issues are already silently solved within the Q40 board. (Which actually was a 68060 design as well. The idea was to offer both.) Peter
