[comp.sys.mac.system] Operating systems history & optimal systems

A few questions.

1) Is there a document available somewhere on Internet (like apple.com)
   which briefly summarizes the various revisions the Mac OS has gone
   through and major features added or changed.

2) I know an Apple document exists specifying an optimal operating
   system revision level for the older Macs (128, 512, 512KE).
   Is it available online and, if so, where?

3) I have heard that some of the commercial services (Compuserve?, Genie?)
   maintain archives which include older revisions of the OS.
   Are similar archives available on Internet?  sumex-aim perhaps?

4) This is the dumb one.  How do I determine the revision level of the
   older system I'm running on my 128?  I haven't found it yet?
   It shouldn't be that difficult, should it?  I've got FINDER 4.1
   but I don't know what rev OS I'm running.  This is embarrassing!
