Performa 631 ram

[68k family]

Why on earth is the max ram in this Mac an odd amount? I haven't tried to put a 32mb simm in the slot labeled 16mb max... But I was curious if anyone ever tried, or modified this?

What's the biggest hard drive you have ever run in one of these? Mine still has the factory 500mb disk.

I would suspect that these machines can accept drives up to 128 GB, like they're contemporary PC counterparts (I'm not 100% certain of this, but it seems logical that it would EDIT: confirmed; ATA-2 (which I believe the P63x uses), is limited to 128 GB). However, you have to take into consideration the fact that the OS must be within the first 8 GB of a given disk, or else it won't boot.

Then there's the issue of having the OS properly recognizing such a large drive (Mac OS 8.1 I think will work better than anything else, since it supports HFS Extended partitions (that are, I think, larger than 4 GB); however, you cannot boot any 68k Mac from an HFS Extended partition- you must have the OS installed on an HFS Standard partition instead. Of course, this doesn't prevent you from actually using HFS Extended on 68k Macs, provided you're running OS 8.1). I don't know if you can like have both a Standard and Extended partition on the same disk, though.

As for the RAM, I have no idea.

The biggest I have tried as 20 gigabyte (used a  powermac laptop hard disk with adaptor) .  Only issue is having 10 partitions as that fills up the screen with drives.  The Mac is limited to 2 gig partitions or less.  

I know the ram limit is laughable as I have a 63X series board with 2 ram slots.  one marked 4 and one marked 32 and I put 32 in both and sees all 64 plus the onboard.  Not sure 128 would work, just remember at the time those may have been the ram limits per chip specs at the time.
