Wanted: 68040!

you usually need an 80mhz crystal for 40mhz operation.

Not for a WarpEngine, unless you want to try to run the CPU at 80 MHz.

A 40Mhz Warp Engine uses an 80Mhz Crystal. ;-)

@ alexh

Did you ever find a 40Mhz 040? I should have a redundant one soon if the price is right!  ;-)

Check again.

I did, ....& guess what!?
...My fooker is 80Mhz!  :roll:

Cyberstorm MKIII uses 80Mhz for 40Mhz 040. Isn't it something to do with a divide-by-two counter on the chip?

I ain't sure & really hope I aint digging a hole here!?  :-?

*edit*

brb.....

Crap! I owe an apology! Please excuse my tardiness!  :oops:

You're quite right, it is 40Mhz. I've had my hands on CSPPC', MKIII' &  Warp Engine borads in the last 60 hours!
Aside from the grief at seeing all this stuff go, I guess i'm getting my "p's" & "Q's" arse about farce!

Humble Apologies!....... 8-)

*edit again*

CSMKIII is 80Mhz for a 40Mhz 040. Definately!  ;-)

No doubt about it, and so does the MKII, but this was about the WarpEngine :-)

I know doctorq & I apologise for my tardiness with confusion on my part. Quite lame really. Sorry!  8-)

I only wanted a L88M variant. I have other hotter ones.

there also the MC68040V which is 3.3v i dont know how hot it run.

AFAIK the 68040V cannot be used with Amiga's because the chips it talks to reply at 5v.

You're not dreaming I've read something like that too, but it must be a feature of either Phase5 boards, or WarpEngine boards because they are uniquely different WRT to this.

Yeah m8, the Phase5 board has a Cap in the CPU socket that you set to either 3.3v or 5v.
I'm guessing one of these 68040V Chips would work fine with the Phase5 board set for the 3.3v required for an 060?
I'd be guessing the Phase5 boards allow the 040 to use it's on-board divide by two counter. Me wonders what a board like this would make of the version V 040 & could you see 50Mhz?
Warp Engine boards usiing 60ns RAM run rings around 060's on the Desktop - even if the 060 uses 60ns RAM. The Warp engine is blazingly fast.  ;-)

...but a CSPPC/CSMKIII card has two Capacitor settings within the socket. In one position, it supply's 5v & the other 3.3v
If the 060 requires 3.3 for operation, where would it draw its 5v power from when the card is set to supply 3.3v?

A WarpEngine 040@40 is faster than an 060@50? I think not. (was that a joke? If so I didnt get it)

Not in terms of MIPS or FLOPS. Just in terms of around the Desktop.
The Warp Engine needs to have 60ns RAM to run at it's fastest capability.
An 060 using 60ns ram on say a CSPPC or CSMKIII card with SCSI III drive is not as snappy on the desktop as a Warp Engine using 60ns Ram on a SCSI II drive.

Go figure?  :-?

[Kin-Hell]

All very interesting stuff.  :-)

[Kin-Hell]

This just got even more interesting!  :-D

Can I have my thread back please!

I've received a couple of offers, just waiting to sort things out now.

Gah mate, ur right!  :oops:

Any Chance one of you Fine Moderators can hack this thread up a bit & re-finger it or summat?

[Kin-Hell]

I wasn't suggesting closing it. Just handing the thread back to the Originator!  :roll:
