Will there be an ACA1240 or ACA1260?

[Iggy]

Yup. It's Mc68060fe133.
Kinda weird looking, and lacking MMU (FPU?), but legit, and capable of 100+ MHz clocks.

Nope, sent an inquiry to Freescale about the part number.

Return message stated the following:
"I can confirm that MC68060FE133 is not a valid Freescale part number".

Who are you going to believe, the company that designed the 68K series or some Chinese vendors?

These are probably relabeled 75MHz MC68EC060s (which lack an FPU).
That chip can be successfully overclocked to 90 or 100MHz.

But that does not alter the fact that the fastest 68060 ever produced was only rated for 75MHz.

[Iggy]

Freescale did not design the 680x0 series.

Freescale for all intents and purposes is Motorola Semiconductor.
They inherited all of Motorola's IP, fabs, and stock.
And they still list several Motorola designed products on their website.
Type Motorola Semiconductor into a Goggle search and see what the first company they point to is.
 

And they deny that there has ever been a 68060 binned and marked above 75MHz.

They also say that chip number is fake.

They ought to now, the 68060 is still part of their product line.

The Natami team has bought into a Chinese falsehood.


Those chips ARE re-marked with a fake ID.

[Iggy]

Maybe.

But if so, well everyone has bought into it since they are the same chips everyone is using these days for fast 060 cards.

As long as they work and are affordable, that is the main thing that ppl care about.

Absolutely, they do work well at 90 or 100MHz and since they're based on some of the last '060s they run cool.

And they're available.
Where as the standard chip (in late masks) is getting hard to find.
I've been offered them for as low as $19.99

I think Peter and Thomas know designation is suspicious.
But I'm impressed with results.

Someone ought to do a math library for these chips.
The FPU on standard '60s wasn't that great anyway.

[Iggy]

I know Freescale denied any connection to these FE CPUs. But...
This is how an FE CPU looks like:



Can you find a pic of the 75MHz MC68EC060 ?
Do they look the same ? If not, then they are not relabeled CPUs.
Copies maybe. Probably. But if they work who cares ? If Freescale doesn't want to push 060s any further I salute the one who does. Hell, give us 200MHz 060 copies in even smaller production process.

All three variants of the 68060 (standard, LC, and EC) were offered in that form (its called a CQFP) and were all pin compatible.

Here's the layout for one.

http://cache.freescale.com/files/32bit/doc/package_info/MC68060PP2.pdf?fpsp=1&WT_TYPE=Packaging%20Information&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation

BGA variants have pretty much replaced this design.

And, of course, PGA is still offered for those that prefer socketed processors.

I don't understand your point.
CQFPs predate BGAs.
And as far as I know, I can't get that much good technical info or illustrations of obsolete parts.

I was lucky to dig up this reference (Freescale has things like this tucked away).
After all, Thomas must have used a similar diagram to create the '060 board based on this package.

But I would be willing to bet that the final masks of EC and LC parts can clock as high as the fictional FE.

[Iggy]

@Chaoslord,

You are so right. When it comes to processors for an FPGA (or original) Amiga, nothing beats a real '060 yet.
And earlier someone mentioned the idea of relabeling '040s as '060.
Since per cycle, the '060 performs better, it  wouldn't be hard to detect.

[Iggy]

@lordaga

Not only do they work really well, but they're still plenty around.
That's why I don't understand why they aren't being used in accelerators.
Sure, there are some challenges (getting around the lack of an FPU is probably the biggest).
But they're cheap!

And since they are usually based on later masks they have less bugs and run cooler (lacking an FPU and MMU helps too).

If we had a good public domain design, we could be using these right now (and they would way out perform an '030).

[Iggy]

Knowing the Chinese, they probably took one 68060 LC/EC apart, duplicated the whole logic and started mass-producing them.

I don't know.
The fact that they're selling the surface mount version instead of a ball grid array makes me  think they're salvaging embedded processors.

A bga can be reused too.
But re-balled is complicated and tedious.

[Iggy]

Check this thread out.

http://boardreader.com/thread/My_68EC060_has_an_FPU_Will_it_have_a_MMU_1jo99Xuiw.html

Apparently LC and EC CPUs don't always have non-functioning FPUs and MMUs.

Although the chips might not run at 75MHz or more while using this parts.

Apparently there are CyberstormPPC cards and Apollo 1260s with EC components installed on them.

Now we know why some of these overclock well.

Anyone with a 1260 willing to install a 75MHz EC processor on it?

I'll even pay to have it done and set up to run at 80MHz.

[Iggy]

The part number on my Apollo 1260 indicates that it is lacking an MMU and/or FPU.  I thought I had been ripped off!
But the MMU an FPU are both in there and they work.

You can't completely trust the markings.

Apparently not.

BTW - BGA 68EC060RC75 is available.

And PGA 68LC060RC75 is available in quantity up to 1000.

I'm getting suspicious that Jens is jerking us around.

Claims the Apollo design is unstable  when users have some running @ 80MHz and also claims 68060s are not available in quantity for production.

WTF?
I'm not sure I have as much faith in the guy as I used to.

[Iggy]

Prices seem pretty high though. Perhaps that's why Jens isn't ordering them.

Pretty much the reason I'd think, too.
Can't make much profit on a board which has a $220 processor (that ought to sell for about $19.95)
Maybe buying "FE133s" isn't so dumb after all.

[Iggy]

$220.00 for just the cpu in 2012 is quite ridiculous.
 
How much are the FE133s?

One company quoted $19.95.
Most slightly higher (although not as silly as US pricing).

[Iggy]

I don't even know where he's got that quote from.

Last I looked, they charged almost $500US at a batch order of 1000.

I think that might have been a quote on 10,000. I'll have to check.
In any case you virtually never have to pay an initial quote price (there's usually room for negotiation.

However, this may not be the case with the 75MHz LC as there appears to be only about a low four digit number of them left (they've long been eol'd).

And most of those are sitting at a distributor that sells a lot of product to arms manufacturers. Those companies will pay a premium to obtain something that has limited availability.

[Iggy]

I.
EDIT: I've been offered a Blizzard 1240 for 280 euros. It's without packaging and without any RAM. Is this one of much greater value than the Apollo 1240 with 32MB I've been offered for 260 euros?
Furthermore, do most accelerators on the used market today come without packaging? I'm kind of reluctant to buy something that isn't in it's original box anymore.

I rarely have the original packaging for what I sell on Ebay.
The point is to make sure it still functions and that the seller warrants it as good.

BTW - I'd go with the one with the RAM.
And modify it for an '060.

[Iggy]

I hope this stuff isn't from ripoffEbay.

Hey! I'm an Ebay seller and so was Redrumloa (who you'll notice doesn't bother posting anymore).

Here's the trick with Ebay.
Check out the seller.
Has he had a fair number of transactions?
Is his feedback rating good?
Mine's 100% positive with over 400 feedback comments.
Next, and this is important, read the description.
If there are any qualifiers (like, hey no guarantees this is functional), don't buy it.
If the seller says its good, even if he's not offering to take returns you're covered.
Because you're going to pay with Paypal (created by the great Elon Musk - yeah the guy that runs Tesla Motors).
If you buy it and it doesn't match the description, contact the seller and file a complaint with Ebay.
If the seller doesn't offer you a fair resolution, Ebay will get you your money back (including the shipping).
After all, they own Paypal and can backcharge the Ahole.

Its that simple.

I've never had a bad transaction following these steps, because if I get screwed I get it all back (and I can keep the piece of crap and even leave negative feedback for the seller which he won't be able to retaliate about).

Like I said, simple.

[Iggy]

(Is it just me, or does the upper right half look like something went up in smoke before?)

To buy or not to buy?


EDIT: Just realized this is a Phase5, so it will only accept single-sided SIMMs.
Is there any way to change this behaviour (some sort of mod)?

Its fine. The fan contacts were obviously soldered by the owner (not a great job, but OK).
