Title: Searching for 68040/40 processor ... for A4000 upgrade !!!
Post by: Effy on August 11, 2004, 07:58:23 AM
I am the happy owner of a http://www.amiga-hardware.com/x-calibur.html (http://www.amiga-hardware.com/x-calibur.html) and I want to use it to speed up my A4000D with 3640. But instead of removing the 25 Mhz 68040 from the 3640 and putting it on the X-calibur, I prefer to put a 40 Mhz version on it and possibly also tune that one a bit to go faster to maybe 50 Mhz ... problem is that I can only find one 68040/40 on Ebay (worldwide), for 27 euro in the States. Does anyone know a little cheaper solution ???

Hi

ask to Vesalia.

They has/had the 33 Mhz 040 with the latest Mask (easy OCable).

I've ordered one 1 year ago . . . .never received it ;-)

Ciao

More than a year ??? That means a year closer to my deatch !!! I would prefer to get it a litte bit faster ...
You say it´s a 33 Mhz that can be overclocked, but how far can you do that ??? Only to 40 Mhz ???

With all due respect to Apple but I decided to go for a 68040/33 processor board for an Apple computer and remove the processor from that. This turns out to be cheaper than buying a seperate 68040 ...
How far can you tune such a 33 Mhz 68040 ???

If you get an apple board make sure the FPU and MMU are working and its not a LC model. I know some of the lower end 68k macs did that back in the day.

Aren´t there also LC versions built into 3640´s ??? Think I read it in the Big Book ...

If I buy a 680LC40 instead of a full 68040 then I probably get down to a level of a normal 68030, not ??? But when I look at the 68060/75 that runs without fpu, does this mean that a 680LC40 can be pushed further than the normal limits ???

Also be warned that some Mac users swap processors, to get the right processor in the right form factor (eg. a "pizza box" with a full 68040).  I tend to dispose of equipment when I do that, but I'm not sure everyone has that philosophy.

And the other thing is: please be careful of the machines you pillage.  Some Macs are a dime a dozen, but others are quite desirable.
