Thanks for any info.

I like the choice of 7.5.3. 7.6.1 gives some modern
goodies not available in
7.5.3, but the latter uses less RAM and can be
modified to include an
Appearance extension to make it look like OS 8.

What System Version to Use? May 1999
(http://micro.uoregon.edu/workshops/macoutline/whichsystem.html),
gives a rather complete discussion on this matter.
They say:
System 7.6.1
Any Macintosh model that has 16Mb of memory or more.
If with any version of System 7.5.3 or higher, you
should update to at least 7.6.1 (or higher) because
for you, this system amounts to bug fixes. If you are
considering an upgrade to 7.6.1 from 7.5.1 or earlier
then moving to 7.6.1 will definitely impact
performance in a very noticible way, yet there may not
be any features in the new OS that you require. The
exceptions being those connected to Ethernet networks
can take advantage of the higher transfer speeds of
OpenTransport built in to 7.6.1 and higher. Memory
requirements for System 7.5.1 can be as low as 2Mb,
where 7.6.1 is going to require around triple that.
Comments: If you decide to upgrade to System 7.6 from
any MacOS version prior to System 7.5.2 be absolutely
certain that you update the SCSI drivers on your hard
drive. You will be given an option to do this when you
run the System software installer.
NOTES: Powertalk is not compatible with 7.6. OpenDOC
and Cyberdog will not work on 68030 or 68040 based
modes. If you do not know what these things are then
this warning does not effect you.

Actually, OpenDoc can be made to work on 68K Macs with 7.6.x, however not by using the
installers included with the system. What you need to do is download OpenDoc 1.2 from
Apple's older software downloads site if you want OpenDoc with 7.6.x.
At the time of 7.6, there was a fairly serious problem with an extension called the
CFM-68K Runtime Enabler. Due to this Apple decided not to include the extension, or
any Apple software that relied on it in the 7.6 release. This problem has scince been
fixed, and software that uses this extension (including OpenDoc, CyberDog, LaserWriter
8.4.x 8.5.x from Apple, and Internet Explorer from that other company)can now work
on 680x0 Macs.
However, there is one extra hurdle to getting OpenDoc, Cyberdog and LW 8.4 on a 7.6
68K system, the included installers only work on Power Macs. Newer installers for
OpenDoc and LaserWriter 8.4.x (or 8.5.1)that do work can be downloaded from Apple's
Older Software Downloads Page (Thes products include a newer version of the CFM-68K
Runtime Enabler). I do not know if or where a version of Cyberdog that would work
could be gotten from.
Note that the 7.6.1 update included version 4.0 of the CFM-68K Runtime Enabler, which
corrected the problems, but did not include any of the Apple software that relied on
this extension.
WARNING!!! Anyone using System Software 7.1.x or 7.5.x on a 68020, 68030 or 68040 Mac
with a version of the CFM-68K Runtime Enabler prior to 4.0 should seriously install
version 4.0 to avoid potential system crashes! The extension is also avalible
seperatly on the Older Software Downloads Page.
P.S. When deciding which OS to run on a LC III, remember that 7.6 takes about twice
the RAM and twice the Hard Drive space as 7.5.5. Whilst 7.6's performance would likely
be OK, you had better be prepared for the disk space and RAm it would consume. (7.6.1
takes about 70MB of hard drive space and 6-8MB RAM on my Centris 650, whilst 7.5.5
takes about 40MB of disk space, and 4-5MB RAM on either the 650 or a LC II. 7.1.1 on
the LC II takes up even less-and is probbly the best choice for performance on '030
Macs, but is a bit light on features. 7.5.5 is, in my opinion, the best compromise
between features, space and performance for a 68030 Mac)
