Didn't Apple use to have a 50Mhz 601 PPC Upgrade for older macs? Does anyone know what happened to it and where i can still get it?

didn't think the LC series had much if any capabilities to upgrade, afterall, LC stand for Low Cost...I have no clue what happened to those upgrades, was going to get one for my IIvx, then decided it wasn't worth it.

The PPC Upgrade fitted inside the PDS slot, the LC series have one PDS slot, so technically it could work, but since PDS slots are different in different kinds of machines, it was made for different series i believe, but i really want to get one for my LC 475.

I wish I could find a PowerPC upgrade for my Mac Quadra 630... I don't use it much anymore, but I'd like it to have a little more horsepower. And no, I don't want to buy a first-gen PowerMac.

Doesn't Sonnet have a PPC upgrade for LC's? If I remember correctly, it even has ethernet built-in.

An LC cannot be upgraded to PowerPC. Sonnet's 68040 "upgrade" is a motherboard replacement, I think.

The 50Mhz PPC Upgrade that Apple offered is compatible with the LC 475, i know this for a fact, i just do not know where to find it.

Not LC. LC 475. BIG difference. LC = 68020 @ 16 MHz. LC 475 is a ... 68040 @ 25 MHz? The '040 without the FPU, though. What's the designation on that again? 68LC040? (Hee hee. I remember the good old days when the Quadra 840AV was king. Still runs wicked fast under MacOS 8.1)

Hehe, 40Mhz of raw power! Makes my Yosemite G3/400 look pathetic!

Anyway, all of the first four LC series and the Performa 475, 476, and the Quadra 605 (damn, what was apple thinking when they gave four names to the exact same comp?!) have the same shape factor, so technically, all you would have to do is get a LC 475 Logic board and smack it into an LC, therefore, after that, you'd be able to upgrade it to a PPC. So if you are an LC owner, just go on eBay and bid on an LC 475 motherboard and then you've pretty much like quadrupled your speed.

There was an Apple and a Daystar upgrade for the 68LC040 Macs.

The Apple version was called the "Macintosh Processor Upgrade." It has a Power PC 601 which will double the speed of the original processor (50 MHz) and had 256 KB level 2 cache

The other was the Daystar PowerCard 601. I believe this came in two configurations, a 66MHz and 100MHz version. As I understand it, they both work in the same way, and it's not using the PDS slot. I have a Daystar card, and the way it works is kind of funky. You pry out the 68LC040 processor (it is connected via a set of pins). On the bottom of the PowerCard (or Apple version) circuit board there is a set of pins identical to the LC040's pins. You then you push the Powercard into the processor's spot. Once it's seated correctly, you insert the LC into the top of the PowerCard. It kind of acts as a "pass through" so you can switch back to the LC040 if you want to do so.

Too bad there were few made and Daystar is out of business. Maybe you can find a PowerCard on eBay at an inflated price.
