The 648 power supply has an extra wire to supply some oddball voltage for the OLED display, and until I investigate further, I don't recommend using a 648 supply anywhere except in a 648, or using anything in a 648 except a 648 supply.
If you wind up needing an image for that 658, here's a WinMFS one:
If you've got the temporarily spare hardware to do it with, I'd be curious as to what happens when you try to boot a 658 with a drive smaller than 1TB with the 652 image on it, and I mean a drive other than one that actually came out of a 652 and might need to go back into one some day.
As I mentioned in the other thread where you asked about reviving the 658, the HD machines, at least the non-XL versions, used two different power supply models by two different manufacturers, and they are interchangeable, so if both your 652 power supplies are the same and the 658 is different, don't panic.
