68060 testing on Replay board

[hooverphonique]

I recently purchased an MC68040 L88M from chinese supplier utsource, which I believe to be fake...

It is a risk. I have visited two suppliers and have an agreement to swap chips I don't like - so it is in their interest to give me good parts. However, I do need to come up with a decent test suite. Reading the PCN is easy and will validate the mask, however I still need to make sure the chip is fully functional.

Edit, they are not fake but may be reprinted - for example mask set changed, or just broken.

I call it a fake if the print on the chip doesn't match the silicon inside exactly, regardless of if it is working or not ;-)
