RAM Doubler - yes, I think the original hard drive had that installed. Unfortunately, the hard drive crashed.

When to use OS 7 and when to use OS 8 on my Centris 650?

RAM doubler was a third party replacement to the memory manager. That's, I'd argue, something to give a go a little later on. The built-in virtual memory on 7.6.1 and 8.1 will work fine.
And yeah, if you have a working CD-ROM drive (I realize that's a bit of a presumption on my part!) I'd say just burn all the discs. There's of course other ways to do this, you could use a 7.5 network access disk and an appleshare-over-appletalk server, for example.

Do you mean to burn CDs of the installed operating system or of the installation sources?
I'd just burn a copy of the Apple Legacy Recovery CD 68k - 1999. It should have every version of every OS you'd be interested in trying between 7.1 and 8.1, along with all the ancillary system extensions and control panels you might want.
It's my go to OS installation disk for any 68k Mac that could run 7.0 and up.
Set it to 1MB on top of your installed RAM for what he's talking about - just having it on.
Not in this case, he isn't short of memory, just enabling the feature for the change in how memory management is done in Mac OS.
I enabled virtual memory from a control panel in OS 8.1. The panel would not allow me to enable anything less than 33MB of virtual memory. Doing so did bring down the memory allocated to the OS to 8MB. That was significant!
@Paralel Is this CD available on the Macintosh Garden or Macintosh Repository? I will be going out this weekend (probably tomorrow) to get some CD-Rs for making boot discs.

Huh, I didn't realize that their version was different from the one I have. I have the May 1999 version. I guess I should provide mine if I compare the two and find they are different.
