The idea is about the 68060 processor made by Motorola, and if it is possible to get a hold of one and upgrade a Quadra from a 68040 to 68060. A 33Mhz to 75Mhz jump in speed could be obtained.

Is anyone willing to try this, or does anyone know of this ever being attempted before?

and you can change the chip multiplier, since I don;t beleive it's done with jumpers, and you'll need a clip on device to do it..

you SHOULD be able to make it work...

either that or your Quarda will FRY like eggs on the sun.

Where it would have been ideal is on an accelerator card. Then you wouldn't have to worry about pins.

I read up about 060's a few weeks back, and I'm sure there was mention of a pin-compatible version, which has the extra pins on the inside of the pin array, so's they just hang free unused when needed in place of 040's... but that may only be useful in systems where the OS/software is 060 compatible. Even the amigas I think, needed some patches to get the OS working on 060's. Worth dreaming about, of course!

That said, from Motorola's 68060 documentation:

quote:

---

The MC68060 delivers up to 3 times the performance relative to its predecessor, the MC68040. Furthermore, the MC68060 bus is very similar in comparison to the MC68040 bus. A socket adapter from Interconnect Systems is available that converts the MC68060 bus to operate in some existing MC68040 systems. For these reasons, the MC68060 is a viable upgrade processor to an existing MC68040-based system.

Section 2.5.10 - What sort of processor upgrades can I do to my Mac without an upgrade card?

You can get a 68010 for your 68000-based Mac; the '010 is pin-compatible with the 68000 and should drop right in. You CANNOT put a 68060 into a 68040-based Macintosh; the '060 is not entirely compatible with the Mac ROMs or the '040 instruction set and would require a major rewrite of a good deal of software in order to work properly. The '020 and '030 are NOT pin-compatible.

The 68882 FPU is pin-compatible with the 68881 and should be used instead where possible. Socketed 68882s are most often found on dead SE/30 and IIfx motherboards and on Daystar Digital PowerCache cards. The 68LC040, which shipped in most Performa and LC Macs with an '040 CPU, can be replaced with a full '040 without the LC designation, thus adding an FPU to the previously FPU-less Mac. A good source of these is a dead Quadra or Centris motherboard.

I already found ot the answer to this question a few months back. The 68060 is not compatable with 68040 based Mac's.

Trash80: I've seen pinouts and other such things for the 060 in a number of places. First place you'll want to check is the motorola semiconductors site. Get yourself a pdf copy of the 060 manual. Most of it was way way way way above my head when I glanced at it, but you seem to know what you're talking about. I'd love to see you do this!!

Alien: You can do that with a SYSTEM EXTENSION?? Bear in mind that I have no idea what I'm talking about when it gets down and dirty like this, but that just sounds silly to me. But hey, remember when we were all positively convinced that 68k's were no good for MP3?...........Most of it was way way way way above my head when I glanced at it, but you seem to know what you're talking about. I'd love to see you do this!!

That's exactly what SoftwareFPU does for the 68LC040.

Great point, Software FPU corrects for hardware thats missing. If taken to the extreme, you create a system patch to run 68k instructions on a PPC, instructions/hardware architecture that's different in almost every aspect. The 060-040 hack pales by comparison to either example, as far as I can tell.

Afriend of mine owns a Milan(Atari clone). He bought it with a 68040 but replaced it with a 68060. He claims they are pin compatible.

No it was my fault I didnt figure out how to use the site properly, sorry will do better next time.

Long live 68k I say.
