So, I've picked up 15 x 68060 E41J mask set devices from two suppliers in China for testing of the daughter boards.
I'll use the Replay board+daughter board and a ZIF socket to do screening at the supplier later.
Running up workbench is not a bad test, but does anybody have ideas on how to do a more thorough test? Is there any CPU test suites I can use to test all aspects of the device?
I also need to read the id register to verify the mask revision.
Any help appreciated!
Cheers,
MikeJ

With Asm-one :
move.l 4.w,a6
lea readPCR(PC),a5
jsr -$1E(a6)
nop
readPCR:
movec PCR,d0
rte
Revision number in d0 is the X : $xxxxxXxx
Et voilà !

Try out some cpu hungry Amiga demos like (in no particular order):

ClickBoom's Quake demo may be a good idea too :-)
Piru's WhichAmiga will also give you information about current cpu mask IIRC.

WhichAmiga can display 68060 rev :)

Too bad SETI@Home or such won't run on m68k ;)

if of any help, seems to be some sort of 040 testing suite:

Good advice.
I'll look into the test suite.
Ideally I would have something fairly automated that says go/no-go and does not take too long. May have a lot of devices to go through.

Any pics of your 060 ?
This one for example is a fake :

I'll take some. Can you tell from the date code etc?

seems someone on natami forum have written some testcases, i might ask around if you dont want to do that yourself.

Written on the 060 : 0124 = year 2001, week 24

Would be great if you could.

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

Why is that a problem? Were they not manufacturing them at that point?

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 had two 060 like on the picture in my hands : my Apollo cannot boot... Certainly because of FPU lacking...
The date code on these 060 are fake too, I think...

just did.

another couple of links obtained in the same context as previous (a1k.org):

Write 68060 test software?
When was the last 68060 manufactured?

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 ;-)
