I agree 7.6.1 would be better but also be sure to upgrade OT to 1.1.2 afterwords.<br />
<br />
Also make sure virtual memory is on unless you know what you are doing with memory use (if you do know then turning it off will improve speed.)<br />
<br />
Speed might be affected by memory control panels memory cache - it should be about 10% of ram but can be as high as 15%.

Thanks for the system advise. &nbsp;For now I think we will keep the machine at 6.1, but if problems occur more, then I will revert back to 7.6.1 as suggested Trembly and Steven. &nbsp;I did optimize with Norton, rebuild and all that maintenence and seems to operating well.

What is the recommended system for a LC575 with 36 Meg memory, 1.2 gig HD. &nbsp;The machine is currently running 8.1, and is very slow. &nbsp;Would 7.5.5 or 7.6 be more appropriate?

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.
