I think you'd have to re-wire. The 3.3V isn't just extra, I think I remember it is instead of GND. It shouldn't be too difficult though?I’m curious as to if the Performa 630 logic board will work in the 5500 case? I think the connector is the same but I seem to recall the 5500 had a 3.3v rail and I’m not sure if that will cause any problems with the older 630 board.
I would look here and work backwards to see what the pin modifications are.

A Takky Upgrade is to fit a logicboard of a PowerPC into the Apple Color Classic. It gives you much more Power than the original components.powercc.org
Were the 63x/64x boards' the same as the 575 board's edge connector? If so it will be easy to work backwards from that mod procedure to make sure no pins are crossing.
my understanding is that the people behind the takky mods in Japan back in the early 2000's was that they reverse engineered the wiring harness, time consuming but not as hard and it would have been to figure out the VGA and hi-res mods....But, the people behind the takky mod should have had access to the wiring diagram of the edge connector of the 5xxx/6xxx line in order to adapt it to the Color Classic? So this wiring diagram should exist somewhere! And if they reverse engineered it from an actual 5xxx/6xxx machine, it’s unfortunate that they didn’t publish it. We shouldn’t have to reverse engineer the reverse engineering.
The Performa 6360 is the one exception to this rule, being PCI-based.@Durosity just for future reference: it may or may not be 100% correct but one thing to remember is that if the model number is x3x0 or lower (applies to anything 3-digits respectively tho) its nubus-based but if its x4xx or higher its pci-based, and thereforeso the basic psu diagram differs between them two groups due to the extra voltage utilized for the pci bus itself
I feel like I read that the OP had a dead logic board and a spare 630 board? I guess it could be an/unusual fun combination if they wanted better compatibility with older 68k software too.Excuse my ignorance but why would someone want to do this? The 5500 is a better board?
Take care, the 3.3v isn't just an extra pin, if you put a 630 into a 5500 harness without precautions it will be shorting the 3.3v.
That is exactly right. In the 630 it's a pair of GND pins, you will be shorting the 3.3 rail of the PSU.Take care, the 3.3v isn't just an extra pin, if you put a 630 into a 5500 harness without precautions it will be shorting the 3.3v.
