Hmm what model Performa ? can you post a picture ? Somewhere in my stacks o crap have some Mac and Power PC stuff....

I may have something, gotta find it/check it out tomorrow.

edit: just as I was going to bed got a precise memory of location of "That one stray Mac part" and it turned out to be for a 9600, with a BGA 604e on it, so don't think it's any good to you.

editII: Funny story, it was actually the 603e I wanted too when I acquired the above part. Phase 5 blizzard power PC amiga accelerators used them, and there was an option to get one with just the 68x00 companion CPU on without the PPC, and I saw PPC mac part for cheap and grabbed it thinking "steal CPU for Amiga accel" but later realised it was a 603e I needed not a 604e. Anyway, doubt any of those will turn up cheap enough to get you a CPU either, or a surplus Iridium comms satellite which were another mentioned application.

I recall seeing a 603e somewhere unexpected, I believe in an old router some years back. But it was BGA, not QFP like on the Performa...

So I fear you're not just looking for a 603e, but also specifically for the QFP variant.

It's a Mac Performa 6360 (same board as the 6400 but in a horizontal case). Not only did the battery leak, but this computer was from a coastal region, and it suffered greatly from salt water vapor that corroded over the years and also aggravated battery corrosion.

When I tried to turn it on, I didn't hear the chime. The power supply is OK, memory modules, cache, and peripheral cards also seem to be ok. It had a 3DFX voodoo3 2000 in the pci slot, which has some rust spots.

I cleaned everything with vinegar and isopropyl alcohol, but as far as I could see, there are no tracks compromised, just the varnish on the pcb that spoiled exposing the copper. The problem was really the processor that lost its legs. I don't have an extremely accurate soldering iron to "play" with trying to rebuild them

Looking around for alternate part numbers from Freescale and Atmel production, which I think went on longest and latest, and even those seem to be going at $75-$150 from shady suppliers that sell quantity not singles.

As far as I can see it looks like you could get a Performa 6400 motherboard for about the same money you'd end up spending on a known good CPU.

Yes, I found one on ebay, the whole problem is that even though it's relatively cheap, I don't live in the US, my currency is 5x more devalued, so it's a significant amount, in addition to the taxes charged for importation into my country. I thought I'd get some equipment I could find within my borders. The Performa are pretty rare around here. Of course, if there's no other solution, I'll have to import.

I have a vast library of mac software, and I thought maybe this would be the ideal machine for this. I have a G4 733 that I use for more modern stuff, but it's mostly OSX, and I thought I'd use that performs with something around 8 or 9, but with great 68k compatibility as well.

I can not find anything with a 603, did find some 604 and G3 spare cpus plus a MC68882FN33A Mathco for a Performa 600 series....

I was thinking maybe I could solder a PLC socket and fit the processor in it, does anyone know how many legs this processor has? (I can't count because I have astigmatism) Is there a plc socket for it?

240 pin (50 + 70 + 50 + 70) for the CQFP Package. Yours is a 160Mhz variant and a faster version (like a 200Mhz) would work but would run at 160Mhz as the 603 board is typically locked like the earlier Performa's with solder cpu's...
if you find a non damaged cpu...
You beat em to it by a minute 🤣

Thank you very much, I looked for schematic all over the internet and I couldn't find it. I needed this to know what the function of the broken pins was.

Apparently, I'm out of some GND, and out of some "A" and "TT" I'll try some tricks, I hope the heat I used to unsolder didn't kill the processor

Unfortunately the processor was severely corroded, and when it touched its legs, it ended up breaking.

I think I found a somewhat workable solution: I have an old ibook g3 500mhz dual usb that suffered an accident, and the only good thing left on it was its motherboard. I will adapt it to the case of the performa by adding 7 USB ports. It's not perfect, but at least it will keep close to the time and run what I wanted to run on it.

Problems and solutions:

CD drive: I don't want to use a laptop so I'll use an IDE/USB caddy to use a desktop dvd drive.

USB: It only has 2 ports, but I will use one of them for a USB HUB with external power.

Power supply: I will acquire a 24v 1.9a that will be inside the case. It will also power the USB hub.

HDD: I will keep the IDE 2.5" HDD, I will just use a 120GB one, perfect for maintaining compatibility with OS9

Cooling: I will use chipset heatsinks under the chips, and the original performa cooler will do the trick.

Volume, led, and power buttons: Everything figured out.

Loudspeaker: It doesn't take a long time to know how to connect it where the lappy's loudspeaker was connected.

Monitor: The ibook originally doesn't do desktop expansion, just mirroring, so I'll have the boot screen on the VGA connector. The problem is that mirroring "splits" the vram in half for each monitor. But I learned a trick via openfirmware that disables the internal screen, releasing all the vram for the VGA.

Floppy drive (auto eject): I still don't know what to do with it.

Phase5 BlizzardPPC! A true LEGEND!!!

do not exist e Blizzard PPC without a Motorola CPU, 68040 or 68060

IDK exactly what I was thinking back then, possible I was going off an early release announcement that described things not ending up available. Think that a Viper PPC was teased for the longest time also, then there were various homebrew accelerators that never went very far.
