silly question about 68060 CPU

[mantisspider]

HI guys,

yes this is a very stupid question but, i had to ask it.

Can i put a 68060 to replace the CPU on a 1230 accelerator board and get it to work?

what mods would need to be made to the board to get it to function as a proper working 68060 for my lovely A1200? "have solder will travel"

cheers guys, yes you may begin the jeering and mocking

No, the front-side-bus design is different.

Realistically, nothing you could do to fix it.

[mantisspider]

eeek, cheers for the call to the real world mate :-)

any accelerator board that would fit one? 1240 board replaced with a 68060?
if not :-( how about a 68040 on a 1230 board?

040 on a 030 board is also a nono. Actually 040s have the same pin-out as 060s. Only 060s run on a lower voltage.

damn this evil world in which we live
cheers guys

haaaaaaang on, does this mean if i replace my 68040 on my 1240 with a 68060 it will work? is this crazy dream going to come true?

[downix]

No, the voltage is different.  You'd fry the 060.

yegads means i actually have to buy a 1260 :-( cant find one anywhere

There are sites all over the net which explain
how to "swap" a 68040 with a 68060.
They are pin compatible (the 'easy' part) but
as has been mentioned the voltages differ, so
in addition to replacing the processor you
must replace the voltage regulator (or by
some means reduce to 3.3v).

If you are brave and have cash to burn you could
also try this:

Don't forget the crystal, a 040 runs on half the speed of the crystal... if you got a 040/40 and just swap in the 060 for the 040 it will run at 80Mhz and probably fry on you right there and then. :-o

You can order one from Vesalia. Viper 1260 with 64mb RAM is about 240eur. The CPU is clocked to 56mhz. It's not as high quality as the Blizzard but comes with two year warranty. Also, I haven't had any problems with it.

@brian,

hi m8, any idea where i can get hold of these crystals, no luck on ebay and cant find any vendors :-(

Well, I have two extra Blizzard 1260 cards, if you're willing to buy. #1 is mint in box with instructions (like new) Phase 5 model which can be installed in a desktop unit as well as tower, and #2 is a DCE model which was designed with tower in mind, however it can also fit in a desktop 1200 unit if you raise it a little bit (the simm slot is under 45' angle, that's why). The DCE model doesn't come with any box/manual (that's how they were sold by DCE...also in mint, like new condition) but I could print you out a copy of a PDF manual, no problem. Both work great and have never ever given me any problems. The DCE model also runs cooler as it features a made in 2002 68060 CPU on it. I would also rate the DCE model as the better one because of this, however Phase 5 model fits more nicely in desktop units. I also have a Phase 5 SCSI-IV kit with box and manual.

I was thinking of Ebaying the stuff, but...a right offer may persuade me not to. :-)

Hi m8,

im in the UK, but yeah sounds like luck falling into my lap :-D hello luck

@x56h34

Oooh, two 68060s for sale? Talk to Vincent! I am sure he'll be happy to hammer out a deal for one of them also :-)

[x56h34]

@Karlos:

Thanks for letting me know.

I also forgot to mention that the Phase 5 model is the standard 68060 with FPU and MMU, clocked @ 50Mhz, and the DCE model is a fancy true 60Mhz 68060 clocked at 66Mhz with FPU and MMU, so it's about 16Mhz faster than the Phase 5 model. It is also so cool, that putting a heatsink/fan on it would be a waste of money and time. ;-)
