I buy anything that's "full 040", and even "anything 060", even EC060 and LC060.

My design uses a large FPGA for all timing generation. The idea is to create all clocks within a single chip and run all components within spec, even if the CPU is clocked higher. This allows pretty much any combination of CPU/RAM clock, where it's most desirable to have whole-number multipliers between the two clocks (such as 40MHz for the 68040 and 120MHz for the 192MB RAM).

In essence, the design is overclocker's heaven, although it won't be user-settable at all. Should I have enough CPUs at one point, the card will work in it's delivered state, and in no other configuration.

Dirkies: Good job on your online research. This does pop a few questions: If the guy is so good at paperwork around founding companies, how would one believe that he *also* has an engineering expertise? His main skills are surely to make a company look legit.

JimDrew: There's a number of toolings you need for such a connector - not just the plastic parts, but also the pins, the bending tools and the insertion tools. Note that the A1200 connector is a good bit wider than most other 1.27mm-edgecard connectors, so standard insertion tools can't be used. My toolings are long paid for (had them made in 2006), which is why I can offer such a good price.
As for 060s from China: I have had shipments coming in through escrow services a number of times: All old stuff, pulled, re-labelled, part of them even 040s. I've done that a total of four times, with four different "sources" from China. All of them actually shipped the same stock to me, which I had to return because it's not what I've paid for. Luckily, I "only" lost the fees for the escrow service, but that's quite some money, given the fact that I only learned not to trust Chinese sources.

I'm not saying that there's no Rev.6 060s out there - it's just highly unlikely that we'll find the actual source without too many people in the middle, who all want to make their cut.
