What's with the attitude? You asked, I answered as best I could, no-one on the Natami team has even though there's a few of them with boards out there including with these chips.
There's no attitude. Sorry for asking people to back up what they are saying.
I get the frustration about finding out more about these parts and where they come from but you have your answer, buy some, mount them on a board with a rom and start dumping output to get what you want.
Sigh.. this is exactly what I'm asking the people that are saying "hey, you hardware guys, you should make board with these super chips or else!?!!?".
I cannot access the section of the forum to get you that information anymore so I'm just repeating what info I remember. The output from the test programs, and the test programs themselves were available to us, the chips were tested and clocked upto 120MHz,
That information would have been interesting. I'm surprised no one can remember what mask these things are though.
They didn't have Motorola based numbering/revision and didn't appear to be repackaged 75Mhz QFP parts. Partly because they were a different physical size to the older QFP parts.
I'm very doubtful anyone would go the the effort to package bare dies or attempt to re-package already packaged dies. For Motorola QFP packages there is a stamp on the underside of the package that says where that die was packaged (For the 68000 series the dies have been fabbed in the US, Japan etc but it seems from the PCNs that most of the parts got packaged in Hong Kong or Mayalsia). You can use the information in the PCNs to verify the datecode on some parts (The PCNs say where parts should have been packaged on certain years).
I've never really cared where they came from
For your own use, yeah, whatever any old working chip will do. You can't ship that in a product as was being suggested..
but speculation has always been that Motorola produced some QFP 68060 chips in China
Motorola never had fabs in China.. and they don't seem to have every packaged chips in China either. Motorola's own documents mention QFP parts though. So it is possible they did produce some that didn't get to the point of general sale.. and some parts broker managed to get hold of them. Even if that is the case they are still a massive unknown and not something you would want to ship in a product.
and so the designs were just blatantly stolen. I doubt we'll ever get an official answer from anyone.
That's where it gets hairy.. no one in China is that crazy. Fab'ing bootleg chips from "motorola designs" would be beyond uneconomical.
