I successfully installed OS 9 Classic Mode on an eMac.  At first, some of my old programs (Thinkin' Things, Millie's Math House, both edmark) ran fine, but as time went on they started jerking and freezing as they ran.  I re-started and it continued to do the same thing.  Any ideas on why these programs run slowly like this?

    Hello Ed,

     

    Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?

     

    How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.

     

    Open Console in Utilities & see if there are any clues or repeating messages when this happens.

     

    In the Memory tab, are there a lot of Pageouts?

    I gathered the info you suggested in previous message, but I was wondering if you could help me interpret it.

     

    Here's what I got:

    In Activity Monitor; System Memory; Page ins/outs = 12277/0.

     

    Memory is listed as 1.024 MB, with 822.11 MB free.

     

    I looked under CPU tab in Activity Monitor and did not exactly now what I was looking for.  What should I do with the CPU #'s?

     

    I opened Console in Utilities & there were any clues or repeating messages.

     

    The 40 MB hard drive has 9 MB free.

     

    I ran the 9.2 CD-based educ. software again.  Some does not boot up.  Some run fine.  Others are choppy at times. 

     

    Anyway, does this info suggest anything to you.  I wonder if it's a compatability issue between System 10.4.11, Classic Mode and the Power PC chip?  Was this common with Classic Mode? 

     

    I thank you so much in adavance dor any suggestions on how to solve this problem.

    Ed

    Pageouts are good.

     

    You could use more than 9GB of free space, biy not the problem here.

     

    Some Classic Games will run fine, others won't run under emulation, others will be slow, some will only run booted from true OS9, & this is more true with Games than other apps, as OSX classic doesn't allow direct manipulation of video.
