I bought one of these from Ebay. The CPU has a part attached on it, not sure for why but I need to remove it. What is the best and safest way of doing that?

It's a heatsink glued on.
I guess the CPU is in a socket? It was soldered in on my MVME board.
You could wrap some wire around the heatsink then while gently pulling, heat the heatsink with a hot air gun. The glue will weaken and it will come off. Then use cold air to cool the CPU.

Personally i leave those heatsinks on. They're really good.

Mine was socketed. I'll try to heat gun and wire method. It interferes with the keyboard while installed on TF1260. I have a low profile copper heatsink with larger surface coverage.

If you get a can of freeze spray, spray it for about 10 seconds, wait a few seconds, then just twist a screw driver in the crack between the heatsink and CPU. It'll come straight off.

I managed to pick up a Nortel NT5D03PB board which has a 68060E cpu. It was $80 inc postage, so worth a punt.
It's coming from the middle east I think so will take a few weeks to arrive. At the time I really struggled to find out what the CPU actually is but I've seen a website post about salvaging the CPU from that board and they stated they were 68LC060RC66's, so the MMU is there but no FPU.
There are some Nortel boards that have full RC 68060 cpu's in like the Motorola MVME 17x boards. But those are quite pricey still.

I mounted the CPU on vise, heated the round heatsink with heat gun at 200 C while gently twisting with pliers. Slightly increased the rotational force and it came off. Thanks again for the suggestions.

I thought I'd share a list of industrial board part numbers ripe for eBay searching. All of these boards should have the full non-EC/non-LC 68060. While many show up on eBay for super high prices, occasionally you can snag a board less than the going rate for a bare 060 and not have to worry about getting a fake chip from China. Ones I have marked with a * are more likely to have a late revision Rev 6 CPU. The Cognex board marked with a - I've seen with both early and late 060s. If the seller has high resolution photos you can usually tell.
