Will there be an ACA1240 or ACA1260?

If everything is so crystal clear you'll have some evidence to back up what you're saying.. If you are really sure about this I will order a tray of them. If they turn out to be relabelled parts or just outright fakes you'll give me my costs back for the parts and making up a test jig right? :roflmao:

The Natami guys tested them, they're exactly what they seem to be, someone just needs to make a board to test them with a regular Amiga. They seem to be a Chinese knockoff, i.e. a replica.

Wherever they come from though they passed all of the instruction tests. Sadly a lot of that stuff is discussed on the "Team" side of the Natami forum and I'm no longer involved over there.

So yes what it requires is someone actually building up a rig to try them. Sorry, no shorter answer to that.

So basically, even the people that have supposedly "tested" them have no idea what they are. If they do work I doubt they are "replicas". There is no profit in reverse engineering the 68060 for the amount of units you could sell. I'm not sure how insane you have to be to imagine anyone in China spending years reverse engineering the 68060 to produce "replicas" of something they might sell a few tens of units of.. but it's pretty high up on the scale.

It is much more likely that one guy in Shenzhen got some other QFP 68060s (rejected parts, recycled parts from telecoms hardware..) and relabelled them and told all the brokers about them... and this is why if you google that part number you get 3 posts from Amiga forums about how great these chips are from people with no evidence than "my friend's mate's sister's dad's mate's next door neighbor's dog's friend apparently used them and said they are ok". Who are the Natami "guys" anyhow? There seemed to be loads of team members when only one person was doing any work and that guy decided to go it alone.. shame not one of all of those team members actually posted anything showing those chips working..

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. 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.

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. Only 120Mhz because past 100MHz there were problems with the sync-zorro interface between Natami and the CPU board rather than a limitation of the chip. 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've never really cared where they came from but speculation has always been that Motorola produced some QFP 68060 chips in China and so the designs were just blatantly stolen. I doubt we'll ever get an official answer from anyone.

@donpalmera
This is one reason I don't bother posting on these or other Amiga forums anymore, personally I'd think the only real future route for an Amiga accelerator board would be using an FPGA or large CPLD depending on cost. You asked about the FE133, I've seen the tests done and answered, as has ChaosLord and all we've got from you is attitude.

Neither is saying that they're genuine, neither of us is saying that we should all rush out and build a board with them. If you're so wound up about what they are or are not then buy one and test it because I don't think that either of us would advocate that as a future chip for us in an accelerator board.

Whatever you do, drop the attitude. You come across as rude bordering on outright insulting.

Please link them then..
Sigh, you followed some forums.. great. These chips very well may have "worked". But as I said.. I have 0.8mm pitch AE package 68SEC000s that don't exist that apparently work too.. would you ship a product based on these parts?

The fact that none of you even brought up the fact that Motorola mentions CQFP parts in their documentation when they apparently don't exist surprises me to be honest. I would have thought you would have mentioned it right away..

Why does it surprise you? We've discussed this rubbish on and off for years, even if we haven't mentioned the part numbers in posts to make it easy for you to find. What exactly should we be guessing you'll "expect" us to mention next? They made QFP parts? Yes. Some of these show up rebadged? Yes.

We know there are parts that exist which Moto' don't list anywhere official. Whoop-dee-doo. So far people have "asked" if it's worth finding out about the FE133 parts, the answer has been "no".
